TL;DR: An AVALANCHE DIODE in cooperative relationship with a UHF or L BAND WAVE TUNING STRUCTURE AMPLIFIERS LOW POWER OSCILLATIONS at a FREQUENCY in the UHF OR L BAN APPLIED to the WAVE-TUNing STRUCTure, IF the AVALANE DIODE is BIASED with a BIAS level SLIGHTLY BELOW the THRESHOLD VALUE at WHICH free running OSCillations TAKE PLACE as mentioned in this paper.

05 Feb 1969TL;DR: A SILICON AVALANCHE DIODE OSCILLATOR for PULSED OPERATION in the UHF or L BAND, which has an EFFCIENCY (40 percent or better) at least equal to that of VACUUM TUBE OSCillATORS OPERATING at these FREQUENCIES, is described in this article.
Abstract: A IMPROVED SILICON AVALANCHE DIODE OSCILLATOR FOR PULSED OPERATION IN THE UHF OR L BAND, WHICH HAS AN EFFCIENCY (40 PERCENT OR BETTER) AT LEAST EQUAL TO THAT OF VACUUM TUBE OSCILLATORS OPERATING AT THESE FREQUENCIES, IS OBTAINED BY UTILIZING AT LEAST THREE SPACED SLIDING SHORT STUB TUNERS AS PART OF A COAXIAL STRUCTURE IN WHICH IS SITUATED THE DIODE.
