Stable FET local oscillator at 11 GHz with electronic amplitude control
Abstract
An 11 GHz FET oscillator with a stable Ba2Ti9O20 resonator has been developed for the local oscillator of a satellite TV front-end. It has good frequency and amplitude stability, low noise and high efficiency; an original amplitude control provides the means for optimization of the mixer drive. A generalized circuit analysis was presented which optimizes the oscillation conditions while avoiding parasitic frequencies.
