Title: | Phase modulation of microwave signals using point contact Germanium signal diodes |
Authors: | Mohanan, P Girijavallabhan, C P Aanandan,C K K G Nair |
Keywords: | Point contact diodes |
Issue Date: | Feb-1984 |
Publisher: | Indian Journal of Radio & Space Physics |
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 |
