A Microstrip line Reflection-Type Phase Shifter for 60 GHz Phased Array
2019 IEEE MTT-S International Microwave Symposium (IMS), 2019A microstrip line reflection-type phase shifter is presented in this paper for 60 GHz mmWave phased array system. Based on the characteristic of varactor diode, an impedance-transforming quadrature coupler and a novel parallel resonant network are designed to extend the phase tuning range.

Effect of Diode Parameters on Reflection-Type Phase Shifters (Short Papers)
IEEE Transactions on Microwave Theory and Techniques, 1976This short paper describes effects of series inductance, shunt capacitance, and resistances associated with p-i-n diodes on the performance of reflection-type digital phase shifters using a shorted transmission line behind a shunt-mounted diode. It is found that the shunt capacitance is the most dominant reactance influencing the phase shift and it ...

E-Band RF MEMS Differential Reflection-Type Phase Shifter
IEEE Transactions on Microwave Theory and Techniques, 2019A systematic approach in the design methodology, leading to the optimization of a differential reflection-type phase shifter (RTPS), is presented. The key parameters of the quadrature coupler and the reflective loads are analyzed for optimum RTPS performance, showing that: 1) equality between the coupling and through transmission coefficients provides ...

A novel reflection-type phase shifter employing defected ground structure
2009 3rd IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2009A new microstrip reflection-type phase shifter based on branch-line directional coupler has been presented. It has a lot of distinct features including compact structure, high range of phase modulation, constant insertion loss and so forth. These characteristics are obtained by adding appropriate varactor to the reflection terminal and employing open ...

E-band reflection-type phase shifter with uniform insertion loss
2018 IEEE 18th Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems (SiRF), 2018An 81–86 GHz reflection-type phase shifter (RTPS) with uniform insertion-loss (IL) for E-Band phased array transceivers is reported in this paper. The RTPS is based on two loaded couplers and implemented in 120 nm SiGe BiCMOS process. The 6-bit phase shifter achieves >195° phase variation across the upper E-band with less than ±0.5 dB insertion loss ...
