“…The achievable bandwidth is very crucial, since it dictates the total system design. Many researchers have already investigated the tunable bandwidth of microwave/ millimeter wave IMPATT oscillators [1][2][3][4][5][6][7][8] . Inspite of considerable work reported in the field of resonantcap IMPATT oscillators, there remains a scope for detailed and coherent study of their tuning properties, specially at Ka-band.…”

The paper describes the studies of the tuning properties of an indigenously developed resonant-cap continuous wave IMPATT oscillator at Ka-band by changing circuit susceptance through mechanical tuning. It was observed that output power of a resonant-cap IMPATT oscillator passes through a maximum at a particular frequency for a given diode with an optimum combination of cap diameter and cap height. An empirical relation has been found between cap diameter 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 the phenomenon of frequency jump in certain positions of sliding short have been studied.
