| Abstract: | An oversized-cavity millimetre-wave IMPATT oscillator has been constructed which can be easily coupled to a groove guide via a simple transformer. A resonant-cap structure is used to determine the frequency of oscillation. The oversized-cavity results in the Q of the oscillator being greater than that of a conventional impatt oscillator, but the output power and frequency are nevertheless stable. The tuning characteristic is discussed and a frequency spectrum presented. |
