Abstract :
A digital phase shifter utilizing three PIN diodes in a tee configuration is described. The operation is explained in terms of low and high pass filter characteristics. Design expressions for phase change, insertion loss and VSWR as a function of element values are given. Frequency characteristics for 45, 90 and 180 degree units are shown in graphical form.
