The RTPS circuit uses a 90º hybrid coupler and two reflective load networks consisting of varactor diodes and inductors. Proper design of 90° hybrid coupler is critical in realizing maximum phase shift. The RTPS circuit implemented on a Rogers Duroid substrate is large in size. We discuss methods to reduce the size of L-band RTPS.

Pełny tekst źródłaThis work focuses on the design of on-silicon mm-wave Reflection-Type Phase Shifters (RTPS) with Oscillation-Based Test (OBT) capabilities. For more consistency, a single technology was considered, the STM 55-nm BiCMOS. First, the theory and practical implementations of 3-dB couplers is discussed. Particular attention is brought to the Coupled Slow-wave CoPlanar Waveguide (CS-CPW) topology, due to its good performance. Using this topology, the measurements of two 3-dB couplers are reported: (i) a 120-GHz, and (ii) a 185-GHz coupler.Next, the existing topologies of integrated varactors are discussed. Measurement results are reported for an Inversion-mode MOS (I-MOS) varactor from 1 up to 325 GHz. Additionally, the Common-Source MOS (CS-MOS) varactor architecture is proposed and measurement results from 1 to 145 GHz for this architecture are reported.Then, the theory of RTPS is presented and CS-CPW-based couplers together with Accumulation-mode MOS (A-MOS), I-MOS and CS-MOS varactors are used for the design of four RTPS. The measurement and simulation results of these RTPS, with central frequencies ranging from 60 to 200 GHz, are presented.Subsequently, the theory and measurement results of the OBT on an integrated 60-GHz RTPS are discussed.Finally, a mm-wave TRL calibration compaction technique is described using machine-learning tools

Pełny tekst źródłaThis manuscript represents the thesis work that mainly deals with the design of RF MEMS switches for reconfigurable circuits. A solution that solves the problem of trapping phenomenon in the dielectric of the switch has been proposed using Ta/Ta2O5 dielectric. This RF MEMS switch, operating at a frequency of 20 GHz, has showed reliable operation without the occurrence of the dielectric-trapping phenomenon. It also gave a high capacitance value of 350 fF and a high capacitive contrast of seven. These components are then integrated into the design of a reflective type phase shifter using the Lange hybrid coupler. The phase shifter guaranteed a 180° phase shift, low insertion losses as well as good isolation below -23 dB.Other RF MEMS switches, using Au/SiN actuation electrode, are used in the design of a 2-bit and a 3-bit phase shifter. The 2-bit phase shifter demonstrated the ability to have a smooth phase shift of 0°, 96° and 186° with an approximate step size of 90°. The PCM phase change materials switches, designed in our XLIM laboratory, were also tested for the design of a phase shifter. The conceived circuit was able to reach the 180° phase shift with, however, high insertion losses. In the last project, we detailed a design of an LC reconfigurable impedance tuner. This impedance adapter is tested on the WolfSpeed CGH40010F transistor and demonstrated a good matching at the output of the transistor at 5 GH. The design of the tuner and its integration into a PCB card on a FR4 substrate are still, however, a matter of concern

Pełny tekst źródła18 GHz frequency band is designed, simulated and partially realized. The designed structure uses one coarse tier, three medium tiers and one fine tier for frequency discrimination. A novel reflective phase shifting technique is developed which enables the design of very wideband phase shifters using stepped cascaded transmission lines. Compared to the classical phase shifters using coupled transmission lines, the new approach came out to be much easier to design and fabricate with much better responses. This phase shifting technique is used in coarse and medium tiers. In fine frequency measurement tier, I/Q discriminator approach is used because reflective phase shifters would necessitate unacceptably long delay lines. Two I/Q discriminators are designed and fabricated using Lange directional couplers that operate in 2-6 GHz and 6-18 GHz, resulting in satisfactory response. Additionally, 6 GHz HP and 6 GHz LP distributed filters are designed and fabricated to be used for these I/Q discriminators in fine tier. In order to eliminate possible ambiguities in coarse tier, a distributed element LP-HP diplexer with 10 GHz crossover frequency is designed and fabricated successfully to be used for splitting the frequency spectrum into 2-10 GHz and 10-18 GHz to ease the design and realization problems. Three power dividers operating in the ranges 2-18 GHz, 2-6 GHz and 6-18 GHz are designed for splitting incoming signals into different branches. All of these dividers are also fabricated with satisfactory response. The fabricated components are all compact and highly reproducible. The designed IFM can tolerate 48 degrees phase margin for resolving ambiguity in the tiers while special precautions are taken in fine tier to help ambiguity resolving process also. The resulting IFM provides a frequency resolution below 1 MHz in case of using an 8-bit sampler with a frequency accuracy of 0.28 MHz rms for 0 dB input SNR and 20 MHz video bandwidth.

The phased array system is the one of the most important technique in the multi-antenna system. By the function of the phase shifter, we can control the beam directions and the signal will be transmitted and received more efficiently. In the thesis, an 11 GHz 4x4 Butler matrix, a 38 GHz single-pole-four-throw(SP4T) switch and a 38 GHz low loss reflective-type phase shifter (RTPS) are proposed. The 11 GHz 4x4 Butler matrix is designed in Rogers board (RO-4003C). The 4x4 Butler matrix provides four different beam directions. From the measurement results, the insertion loss are 7~10 dB, the return loss are above 10 dB and the error of phase difference are about ±15°. The 38 GHz single-pole-four-throw(SP4T) switch is designed and implemented in TSMC 0.18 m CMOS technology. The switch is used to choose the different output paths. From measurement results, the insertion loss are 6.2 dB, the isolation are 25 dB and the return loss are 6 dB. The 38 GHz low loss reflective type phase shifter is designed and implemented in TSMC 90 nm CMOS technology. The negative resistance is used in reflective load for compensating the loss of phase shifter. From measurement results, the insertion loss are 1.45±0.35 dB, the phase tuning range is 161°, the return loss are above 10 dB, the linearity(Pi,1dB) are -9~-3 dBm and noise figure are 9~12.5 dB under different tuning voltage. The DC power consumption is 9.6 mW from 1.2 V supply.

This thesis includes two parts. In the first part, the 180° hybrid ring with a center frequency of 2.5GHz and excited by the balanced microstrip line is designed. By replacing a half wavelength transmission line with an ideal phase inverter, the 180° hybrid ring exhibits a wide bandwidth of almost 120% and the size reduced for 50%. In the second part, by using the broadband 180° hybrid ring designed in the first part, the broadband 180° reflection type digital phase shifter has been realized. Unlike the conventional reflection type phase shifter where two PIN diodes are connected to a 90° hybrid ring with the same bias condition, in the proposed phase shifter two PIN diodes are connected to the 180° hybrid ring with opposite bias condition. The proposed one can get much wider bandwidth with almost the same insertion loss in two phase states. The whole circuits in this thesis are fabricated with microstrip line on a RO4003 substrate with a dielectric constant of 3.58, a thickness of 20 mil.

In this thesis work, several reflection-type phase shifters where studied, designed and measured the varactor diodes are loaded on couplers so that reflection coefficient can be varied based on different DC bias. In 2 GHz reflection-type phase shifter with single resonator design three structures including symmetric branch line, asymmetric branch line and quasi Wilkinson power divider were fabricated on FR4 with 0.4 mm thickness. The asymmetric branch line uses the difference of reference characteristic impedances to broaden the tunable phase range. However, the insertion loss will be increased as well due to the impedance mismatch. By adding a shunt compensation resistance, less than 1 dB insertion loss variation is achieved. For 915 MHz system application, the method of short-open-short is adapted fabricate a full 360o phase shifter, the measured results >15 dB return loss and 6 dB insertion loss. Finally, A MMIC reflection-type phase shifter based on TSMC 0.18 μm COMS process was designed, and currently under fabrication. A performance of 0.03 dB insertion loss variation; ~200o phase tuning range and > 12 dB input return loss was predicted by the simulation.
