Abstract
Design and performance of analog phase shifters using hyperabrupt varactors with linear phase versus voltage is presented. Phase linearity of 22 degrees per volt +-8 percent was achieved for a 100 degree S-band device with a phase deviation of 1 degree from linearity. At X-band, linear phase control of 270 degrees was achieved. The selection of the varactor diode capacitance versus voltage and matching circuits for linear performance are presented.
