Abstract
A monolithic IMPATT (impact avalanche transit time) oscillator operating in the 50-GHz region has been controlled in frequency in an open microwave resonator. The noise spectrum of the oscillator in a closed quasi-optical cavity showed substantial improvement when compared to oscillation in free-space. These results show that monolithic circuits are compatible with open-resonator techniques, which can lead to improved monolithic oscillator stability.<>
