Abstract
A reflective hybrid analog phase shifter is detailed which is operable in the X-band, and which exhibits minimal phase shift variation with higher power loadings. A pair of back-to-back connected Schottky varactor diodes are serially connected to each of the phase shifting ports of a 3 dB coupler. The Scottky varactor diodes are reverse biased to permit continuous variation of the phase shift as a function of analog bias potential. A monolithically fabricated implementation of this circuit design is detailed.
