Title: Phase modulation of microwave signals using point contact Germanium signal diodes
Author: Mohanan,P; Girijavallabhan,C P; Aanandan,C K; K G Nair
Abstract: A forward - biased point contact germanium signal diode placed inside a waveguide section along the E -vector is found to introduce significant phase shift of microwave signals . The usefulness of the arrangement as a phase modulator for microwave carriers is demonstrated. While there is a less significant amplitude modulation accompanying phase modulation , the insertion losses are found to be negligible. The observations can be explained on the basis of the capacitance variation of the barrier layer with forward current in the diode
