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 excellent frequency and amplitude stability, low noise and high efficiency. An original amplitude control provides the means for optimisation of the mixer drive. A generalised circuit analysis will be presented which optimises the oscillation conditions whilst avoiding parasitic frequencies. Complete measurements will be given.
