Sets of driving oscillators with fast frequency switching

Abstract

Recently, multiple frequency oscillator units providing the switching of stable microwave signal sources have attracted considerable interest. These units provide a frequency switching rate below 5 /spl mu/s while retaining the parameters of an individual dielectric resonator (DR) stabilized microwave oscillator. These oscillator units use sharp suppression and excitation of self-induced oscillations in the oscillator circuit, in addition to a high-speed multichannel p-i-n switch (up to 10 channels).
