Abstract [eng] This work investigates Reflection Type Phase Shifters and compares and optimises three different phase shifter models. The operating frequency is 3.5 GHz and the measurements are done at 3.3 GHz, 3.5 GHz and 3.8 GHz frequencies. Reflection coefficients, insertion losses, phase shift and VSWR are measured. A reflection coefficient which is more negative than -15 dB, insertion loss which is more than -2 dB and a minimum VSWR value are expected. The behaviour of the different models of phase shifters is analysed based on these requirements. Other than these parameters, the bandwidth performance of each model is also compared. Phase shifts against variable load graphs are plotted using MATLAB for each model.
