Full textIn this dissertation, a signal generation structure is proposed using which a multitone Local Oscillator (LO) signal is created by a single I/Q modulator. These LOs can be used in the CA receivers to down-convert the transmitted component carriers simultaneously. The multi-tone LO signal structure is further developed to be used at the transmitter as a CA generation solution. Using the proposed structure n-component carriers can be generated in parallel. This structures requires lower sampling rates with respect to the case where RF signals are synthesized directly by digital-to- analog converters. Moreover, less circuitry is required, because one single I/Q modulator is used to generate n component carriers, instead of n I/Q modulators. This work follows on investigating the origin of impairments and mild nonlinearities in our I/Q modulator. To overcome these problems, we focus on the functionality of the overall system rather than each component of the I/Q modulator. This method is called behavioral modeling. Once the nonlinear model is obtained, if its inverse function is applied to the input, a linearized output is expected. The generation of the inverse function is called Digital Pre-Distortion (DPD). We propose a tri-band behavioral model for nonlinearities and impairments in tri-band CA using our I/Q modulator. Furthermore, the DPD of the model is evaluated in simulations and experiments

Full textAs part of a collaborative project between the XLIM laboratory (UMR 7252 of the CNRS and the University of Limoges) and the IPHT research laboratory located in Jena, Germany, my thesis project consists in the development of a widely tunable dual-wavelength synchronous pulsed thulium doped fiber laser for the realization of an efficient and tunable terahertz source. Based on the use of two volume Bragg gratings (VBGs) and a double-clad, polarization-maintaining thulium doped fiber (core diameter = 20 μm) manufactured by the REPUSIL method, a widely tunable single-wavelength laser and dual-wavelength laser has been realized and studied in continuous regime. A tunability of 1 nm to 144 nm was obtained with a power more than 4.5 W and a good signal-to-noise contrast (~ 45 dB) and a spectral linewidth less than 0.1 nm. In pulse regime, an acousto-optic modulator (AOM) was used in free space in the laser cavity to generate the pulses. The double-clad fiber has been replaced by a large-core thulium doped fiber (40 μm) called FA-LPF to to fend off the threshold of non-linear effects and work with a short fiber to decrease the pulse duration and increase the peak power of the obtained pulses. A widely tunable (from 3.8 nm to 120 nm) Q-switched dual-wavelength synchronous-pulsed thulium-doped fiber laser was developed with a peak power more than 8 kW and a pulse duration around 26 ns obtained independently of the value of Δλ at 1 kHz of repetition rate. A contrast higher than 20 dB was obtained limited by the FWM peaks generated for Δλ values below 45 nm. The spectral linewidth of the laser measured at 3 dB of the maximum was less than 0.3 nm

In this paper, the design principles and implementation techniques of I/Q modulator are investigated. The I/Q modu- lator consists of DBMs(double-balanced mixers), phase shifter and power splitter/combiner, where each subcircuit has its distinct electric characteristics. To verify the theoretical results, we build the subcircuit by employing FR-4 boards, mixers and ferrite core. The measuremental results of each subcircuit and integrated I/Q modulator are discussed throu- ghly. We find that the characteristics of DBM dictate the per- formance of I/Q modulator.

The purpose of this dissertation is to develop a Power Amplifier and an I/Q Modulator in a V-band millimeter-wave transmitter system. They are fabricated on TSMC 90 nm 1P9M RF CMOS process. With the development of wireless communication technologies, radio frequency integrated circuit tends to higher frequency, higher data rate, wider bandwidth, and higher integration. For this subject, unlicensed multi-GHz bandwidth around V-band makes very high data rate transmission feasible. We adopt CMOS technology. It has the advantages of small size, low cost, low power consumption, and high level of integration, all of which are for MMW applications. To develop a Power Amplifier and an I/Q Modulator in a V-band millimeter-wave transmitter system. We are using Agilent ADS software and SONNET software to be the simulation tools. The first circuit is Power Amplifier, which utilizes three-stage common source configuration amplifier. The first and second stages are drive stages. The third stage is power stage. To purpose higher linearity, we combine a Pre-distortion Linearizer on the power stage. The circuit will have better linearity than without Linearizer. The second circuit is I/Q Modulator, which is using two Modified Gilbert-cell Mixer, one Coupler, and one Wilkinson Combiner.

The purpose of this study is to generate pulsed Ince-Gaussian(IG) lasers in end-pumped solid-state lasers and to reach different modes of selection and application of Q-switched pulsed lasers. The active Q-switch we adopting in this study is the acousto-optic (AO) modulator. However, we also adopt the chopper in this study. In the first part of the experiment, both of laser systems can be used to generate pulsed IG laser and observe the relaxation oscillation (RO). The second part of the experiment, we study on Q-switched Ince-Gaussian laser generation with AO modulator. Experimental result shows that, using AO Q-switched laser system, this study successfully generates pulsed IG lasers of several different modes. Besides, by classifying IGMs into even and odd groups, this study gives discussions on the relation between pulsed Ince-Gaussian lasers of different modes.
