Abstract
Possible systems for stabilization of a solid state microwave oscillator using a high Q-resonator, as the reaction and the transmission systems (including the Kurokawa system) are considered from a common theoretical point of view. This is achieved by using the scattering matrix representation of a resonant waveguide junction with four output leads, one of which is coupled to a "generator" containing the active device. Conditions are found, that have to be imposed on the circuit and the device impedance locus to obtain a large stability and stabilization range. Is is found that for use in microstrip technique the transmission system is most suitable in view of the much larger stabilization range. The construction of an Impatt oscillator in microstrip technique, which is intended for use in a 20 GHz relay system, is described and measuring results are reported.Keywords
