Abstract : A 1750 mc/s tunnel-diode oscillator for use as a UHF telemetry transmitter in high velocity gun launched projectiles is described. The results of performance tests under high acceleration conditions are discussed. Performance deficiencies are noted. Because of the recent developments in high frequency transistors and current availability of transistor oscillators with power outputs of 100 to 500 milliwatts at 1750 mc/s, it is not planned to continue the work on tunnel oscillators.
