AbstractThe paper describes the studies of the tuning properties of an indigenously developedresonant-cap continuous wave IMPATT oscillator at Ka-band by changing circuit susceptancethrough mechanical tuning. It was observed that output power of a resonant-cap IMPATToscillator passes through a maximum at a particular frequency for a given diode with an optimumcombination of cap diameter and cap height. An empirical relation has been found between capdiameter and wavelength of the optimised oscillator, which agrees with the theoretical relation.The effect of sliding short tuner position on the oscillator at optimised condition and thephenomenon of frequency jump in certain positions of sliding short have been studied.
