Abstract (sommario):

We report cryogenic noise temperature and gain measurements of a prototype heterodyne receiver module designed to operate in the atmospheric window centered on 150 GHz. The module utilizes monolithic microwave integrated circuit (MMIC) InP high electron mobility transistor (HEMT) amplifiers, a second harmonic mixer, and bandpass filters. Swept local oscillator (LO) measurements show an average gain of 22 dB and an average noise temperature of 87 K over a 40 GHz band from 140 to 180 GHz when the module is cooled to 22 K. A spot noise temperature of 58 K was measured at 166 GHz and is a record for cryogenic noise from HEMT amplifiers at this frequency. Intermediate frequency (IF) sweep measurements show a 20 GHz IF band with less than 94 K receiver noise temperature for a fixed LO of 83 GHz. The compact housing features a split-block design that facilitates quick assembly and a condensed arrangement of the MMIC components and bias circuitry. DC feedthroughs and nano-miniature connectors also contribute to the compact design, so that the dimensions of the moduleare approximately 2.5 cm per side.

AbstractThis paper presents the design and characterization of a D-band (110–170 GHz) monolithic microwave integrated direct carrier quadrature modulator and demodulator circuits with on-chip quadrature local oscillator (LO) phase shifter and radio frequency (RF) balun fabricated in a 130 nm SiGe BiCMOS process withft/fmaxof 250 GHz/400 GHz. These circuits are suitable for low-power ultra-high-speed wireless communication and can be used in both homodyne and heterodyne architectures. In single-sideband operation, the modulator demonstrates a maximum conversion gain of 9.8 dB with 3-dB RF bandwidth of 33 GHz (from 119 GHz to 152 GHz). The measured image rejection ratio (IRR) and LO suppression are 19 dB and 31 dB, respectively. The outputP1dBis −4 dBm at 140 GHz RF and 1 GHz intermediate frequency (IF) and the chip consumes 53 mW dc power. The demodulator, characterized as an image reject mixer, exhibits 10 dB conversion gain with 23-dB IRR. The measured 3-dB RF bandwidth is 36 GHz and the IF bandwidth is 18 GHz. The active area of both the chips is 620 µm × 480 µm including the RF and LO baluns. A 12-Gbit/s QPSK data transmission using 131-GHz carrier signal is demonstrated on modulator with measured modulator-to-receiver error vector magnitude of 21%.

Abstract (sommario):

We have developed a multichannel software defined radio-based transceiver measurement system for use in general microwave tomographic applications. The unit is compact enough to fit conveniently underneath the current illumination tank of the Dartmouth microwave breast imaging system. The system includes 16 channels that can both transmit and receive and it operates from 500 MHz to 2.5 GHz while measuring signals down to −140 dBm. As is the case with multichannel systems, cross-channel leakage is an important specification and must be lower than the noise floors for each receiver. This design exploits the isolation inherent when the individual receivers for each channel are physically separate; however, these challenging specifications require more involved signal isolation techniques at both the system design level and the individual, shielded component level. We describe the isolation design techniques for the critical system elements and demonstrate specification compliance at both the component and system level.

Abstract (sommario):

Abstract This paper presents a 26-Gb/s CMOS optical receiver that is fabricated in 65-nm technology. It consists of a triple-inductive transimpedance amplifier (TIA), direct current (DC) offset cancellation circuits, 3-stage gm-TIA variable-gain amplifiers (VGA), and a reference-less clock and data recovery (CDR) circuit with built-in equalization technique. The TIA/VGA front-end measurement results demonstrate 72-dBΩ transimpedance gain, 20.4-GHz −3-dB bandwidth, and 12-dB DC gain tuning range. The measurements of the VGA’s resistive networks also demonstrate its efficient capability of overcoming the voltage and temperature variations. The CDR adopts a full-rate topology with 12-dB imbedded equalization tuning range. Optical measurements of this chipset achieve a 10−12 BER at 26 Gb/s for a 215−1 PRBS input with a −7.3-dBm input sensitivity. The measurement results with a 10-dB @ 13 GHz attenuator also demonstrate the effectiveness of the gain tuning capability and the built-in equalization. The entire system consumes 140 mW from a 1/1.2-V supply.

Abstract For nearly 30 years, we have been designing and supplying instruments for microwave diagnostics of high temperature plasma. This report provides a description of the mm-wave components we utilize to make diagnostics within the frequency range of 26–330 GHz. While most of these components are standard and readily available on the market, we have also developed a few specific devices that simplify the architecture of our instruments. The article includes descriptions of these devices: Backward Wave Oscillators (BWO), Impact Ionization Avalanche Transit-Time diode (IMPATT) sources, IMPATT Active Frequency Multipliers (AFM), Noise Sources, and Electronically Controlled Attenuators. Furthermore, we offer an overview of the microwave plasma diagnostics we have supplied, including ECE radiometers operating at 50–220 GHz, as well as heterodyne interferometers operating at fixed frequency 94 GHz, 140 GHz, or 300 GHz. We also discuss methods employed to ensure measurement stability and present the achieved results. The advent of the new era of modern Monolithic Microwave Integrated Circuit (MMIC) based devices has brought forth exciting possibilities. As an example, we discuss the upgrade of the low noise receiver for the Collective Thomson Scattering (CTS) diagnostic at Wendelstein 7-X, which enables ion temperature measurements in the plasma core [1]. Lastly, we provide a list of MMIC-based devices that are currently available and have garnered the attention of the plasma diagnostics community.

Abstract (sommario):

Abstract A prototype of a compact coherent fast frequency sweeping RF back-end is being developed at IPFN-IST using commercial Monolithic Microwave Integrated Circuits (MMIC). On this work we present the usability of this concept of compact reflectometry associated with a Direct Digital Synthesis (DDS) source. Flexibility is one of the design goals for the back-end prototype, so that it can easily match the required frequency range. The backend alone covers the NATO J-band (10 GHz to 20 GHz) and is designed to drive external full band frequency multipliers, resulting in an ultra-wideband coverage of up to 140 GHz. FM-CW radar precision is strongly dependent on the probing source linearity. DDS nowadays plays an important role in signal generation in many fields of applications for communication systems as well as in radar technology. Modern DDSs are fully integrated, low-cost, single chip solutions that only need an external clock source for generating sinusoidal output signals up to several gigahertz. The DDS benefits from the totally digital generation of the output signal, which allows full control of the signal’s frequency and phase, both with very high precision and resolution. Recent implementations feature automatic sweeping capability, thus allowing the DDS to generate very linear and agile frequency chirps, assuming a high quality and constant frequency reference clock source. We propose to implement a DDS signal generation solution with the capability of a full band sweep in 1 μs. On the receiver side the IF and reference signals will be digitised allowing the use of high flexible data processing techniques. Input/output signals will allow the synchronisation of several systems.

Abstract (sommario):

L’augmentation constante du nombre de capteurs dans les voitures modernes, assurant desfonctions d’assistance à la conduite, font du radar automobile un élément essentiel de la voitured’aujourd’hui et de demain. Cette tendance contribue à plus long terme au développement duvéhicule autonome. L’industrie automobile considère un changement du standard radar actuelà 80 GHz vers une nouvelle bande de fréquence autour de 140 GHz. Ce saut en fréquencepermettrait de réaliser des capteurs plus compact tout en maintenant voir en améliorant laprécision du capteur, grâce aux applications MIMO notamment. Le travail de cette thèse consisteà estimer la faisabilité d’un récepteur radar fonctionnant à 140 GHz.Une première partie de ces travaux se concentre sur le développement d’outils de travail etde modèles pour permettre l’implémentation de circuits intégrés à des fréquences millimétriques.D’abord, une méthode de conception de réseaux d’adaptations d’impédances à bases de transformateursintégrés est présentée. Grâce à leurs nombreux avantages en plus de leur capacitéd’adaptation d’impédances, ils seront constamment utilisés dans la suite de ces travaux. Ensuite,un modèle complet est proposé pour décrire le comportement multi-harmoniques des circuitspassifs appelés N-path et notamment des mélangeurs. Leurs avantages en termes de bruit,consommation et linéarité les rendent adaptés à l’implémentation de radars à 140 GHz.Un deuxième axe de travail consiste à l’implémentation de plusieurs ‘front-ends’ RF pourrécepteurs radar basés sur une architecture appelée ‘mixer-first’. Deux solutions sont d’abordprésentées, exploitant au mieux les avantages des mélangeurs N-path modélisés. Une premièresolution fondamentale est proposée et est conforme aux contraintes de l’application des radarsà longue portée. Une alternative sous-harmonique dotée d’une portée légèrement réduite estensuite développée. Elle permettrait d’importantes économies sur la surface et la consommationde la puce, ce qui répondrait aux demandes du marché pour un produit moins cher que l’onpourrait intégrer en plus grand nombre dans un véhicule.Enfin, un groupe innovant de mélangeurs passifs, appelés mélangeurs ‘bottom-plate’, estétudié pour concevoir deux nouveaux ‘front-end’ RF. Ce type de mélangeur garde les avantages desmélangeurs N-path traditionnels tout en présentant un gain en tension significatif. Un premierrécepteur fondamental est conçu, basé sur une topologie existante aux fréquences RF seulement,pour répondre aux contraintes de l’application radar à 140 GHz. Un deuxième récepteur estensuite développé grâce à une nouvelle topologie de mélangeur sous-harmonique qui a étédéveloppée dans cette thèse. Ces deux nouvelles versions permettent d’améliorer la distance dedétection du module radar
The constant increase in the number of sensors in modern cars, fulfilling advanced driving assistancefunctions, places the automotive radar as an essential element in today’s and tomorrow’svehicle. This tendency is motivated in the long term by the development of autonomous vehicles.The industry considers moving the automotive radar product from the current standard around80 GHz to a new frequency band around 140 GHz. This increase in the operation frequency wouldenable more compact sensors while maintaining and even improving the sensor accuracy thanksto MIMO applications. This work aims to assess the feasibility of a radar receiver at 140 GHz.A first part of this work is dedicated to the development of design tools and models which facilitatethe implementation of millimeter wave circuits. First, a design methodology for impedancematching networks based on integrated transformers is presented. Thanks to their numerousadvantages in addition to their impedance matching capability, they will be used in all thefollowing development of this work. Then, a complete model of the multi-harmonic behaviorof passive N-path circuits and more particularly N-path mixers is proposed. Their benefits interm of noise, current consumption and linearity make them suitable for the implementation of140 GHz automotive radars.A second part of this work is focused on the implementation of multiples RF front-ends forradar receivers, based on a mixer-first architecture. Two solutions are first proposed which fullyexploit the advantages of the modeled mixers at the considered frequency. A fundamental solutionis proposed which complies with the long-range radar applications. A sub-harmonic alternativewith a slightly reduced range is then presented. It would enable significant savings on the chiparea and the current consumption, answering to a market demand for low-cost radar productsthat can be embedded in large number inside one vehicle.Finally, a novel type of passive mixers, called bottom-plate mixer is studied to design twoadditional radar receivers front-ends. These mixers keep the advantages of the traditional N-pathmixers while also presenting a high voltage gain. A fundamental receiver is proposed, based onan existing topology at RF frequencies only, that addresses the constraints for the 140 GHz radarapplication. A second sub-harmonic receiver is designed with a novel topology developed in thiswork, which complement the first receiver. These two front-ends allows a longer detection rangefor the radar module

Doctor en Ingeniería Eléctrica
Este trabajo presenta el diseño, construcción y caracterización de dispositivos para receptores radioastronómicos en las bandas Q (30-50GHz) y W (80-110GHz). Por un lado, el dispositivo desarrollado para la banda Q es de interés para la banda 1 del telescopio argentino-brasileño LLAMA (Long Latin American Array). Por otro lado, los componentes de banda W pueden ser utilizados en la banda 3 de LLAMA o en posibles mejoras para el Telescopio Austral de Ondas Milimétricas (SMWT) que es mantenido por nuestro grupo. Para la banda Q, se diseñó y construyó un amplificador de bajo ruido utilizando un esquema hibrido de integración. Se integró un transistor de alta movilidad electrónica (HEMT) y un circuito integrado monolítico de microondas (MMIC) obtenido comercialmente. Con este diseño una temperatura de ruido inferior a 20 K y una ganancia superior a 30 dB pueden ser obtenidas. En la banda W se desarrollaron varios componentes. En primer lugar, se empaquetaron amplificadores comerciales MMIC de las compañías OMMIC y HRL. Al ser medidos a 15K estos amplificadores de bajo ruido alcanzaron temperaturas de ruido menores a 100K y ganancias superiores a 17 dB. Dada su disponibilidad comercial se determinó que son apropiados para ser utilizados como segundo amplificador en un receptor. Segundo, utilizando diodos Schottky comerciales, se fabricaron mezcladores sub-armónicos que cubren la banda W extendida. Las técnicas de desarrollo han variado desde el uso de componentes discretos hasta el diseño de MMICs para reducir el tamaño de los mezcladores. Los componentes mencionados previamente han sido ensamblados en un módulo compacto que puede ser utilizado en la etapa de mezcla de frecuencias. Este módulo posee una temperatura de ruido menor a 800 K y ganancia superior a 2dB a temperatura ambiente. Finalmente, se construyó una antena de ranura cuyo perfil ha sido optimizado para mejorar sus principales características (reflexiones, ancho de banda, polarización cruzada y simetría de haz). Entre las antenas de su tipo, esta es la única que posee un perfil optimizado lo que ha permitido obtener el mejor funcionamiento alcanzado hasta el momento.

Abstract (sommario):

A 690 GHz wide spectral bandwidth heterodyne receiver was developed to observe the J=6-5 rotational emission line of carbon monoxide (CO) in extragalactic sources. This receiver is based on a niobium superconductor-insulator-superconductor (SIS) mixer with a twin-slot antenna in a superconducting NbTiN ground plane. A 4-8 GHz low-noise amplifier was developed to amplify the intermediate frequency (IF) signal from the mixer with a spectral bandwidth of 1,700 km/s, enough to comfortably observe the entire emission line of the broadest extragalactic submillimeter sources with a single receiver tuning. This amplifier is a quasi-monolithic microwave integrated circuit (QMMIC); three 160 micron gate InP high-electron-mobility transistors (HEMTs) were bump-bonded to a thin-film GaAs substrate containing passive tuning and DC bias circuitry. The measured amplifier gain is 32 dB and the noise is approximately 8 Kelvin from 4 to 8 GHz at a physical temperature of 4 Kelvin. The complete receiver achieves a measured uncorrected double-sideband noise temperature of 180 Kelvin. Prior to this development effort, a versatile microwave simulation package was written to calculate and optimize the signal and noise performance of high-frequency circuits, especially those containing superconductors and superconducting tunnel junctions. Using this package, called SuperMix, C++ programs can be written to simulate and optimize circuits of arbitrary size, complexity, and topology. SuperMix was used to simulate the complete 690 GHz SIS receiver. The receiver was used at the Caltech Submillimeter Observatory (CSO) to map the 12CO J=6-5 emission line in the central kiloparsec of the nearby starburst galaxy M82 at a resolution of 14 arc seconds. Hot spots were found on either side of the dynamical center. A novel deconvolution technique was used to compute a 12CO J=6-5 / 12CO J=2-1 line ratio map based on high-resolution J=2-1 interferometer data. The 12CO J=6-5 map, along with observations of 12CO J=4-3, 12CO J=3-2, 13CO J=3-2, an upper limit for 13CO J=6-5, and five other measured CO lines from the literature, were analyzed in the context of a two-component large velocity gradient (LVG) excitation model. Likelihood curves were calculated for each of the model parameters as well as a variety of related physical quantities for the two hot spots based on the measured line intensities and their associated uncertainties. This approach reveals in an unbiased way how well various quantities can be constrained by the CO observations. The results of this analysis suggest that the warm gas is less dense than the cool gas, and that over half of the total molecular gas mass in these nuclear regions is warmer than 50 K

Abstract (sommario):

The global land use implications of biofuel expansion have received considerable attention in the literature over the past decade. Model-based estimates of the emissions from cropland expansion have been used to assess the environmental impacts of biofuel policies. And integrated assessment models have estimated the potential for biofuels to contribute to greenhouse gas abatement over the coming century. All of these studies feature, explicitly or implicitly, competition between biofuel feed stocks and other land uses. However, the economic mechanisms governing this competition, as well as the contribution of biofuels to global land use change, have not received the close scrutiny that they deserve. The purpose of this paper is to offer a deeper look at these factors. We begin with a comparative static analysis which assesses the impact of exogenously specified forecasts of biofuel expansion over the 2006-2035 period. Global land use change is decomposed according to the three key margins of economic response: extensive supply, intensive supply, and demand. Under the International Energy Agency’s “New Policies” scenario, biofuels account for nearly one-fifth of global land use change over the 2006-2035 period. The paper also offers a comparative dynamic analysis which determines the optimal path for first and second generation biofuels over the course of the entire 21st century. In the absence of GHG regulation, the welfare-maximizing path for global land use allocates 170 Mha to biofuel feed stocks by 2100, with the associated biofuels accounting for about 30% of global liquid fuel consumption. This area expansion is somewhat diminished by expected climate change impacts on agriculture, while it is significantly increased by a moderately aggressive GHG emissions target and by advances in conversion efficiency of second generation biofuels.
