A Study of Inter-Injection-Locked Phased Arrays

Abstract

Progress in monolithic fabrication of microwave integrated circuits has led to reduced size and weight as well as improved performance of many microwave systems. At the shorter microwave and millimeter wavelengths, however, currently available solid-state devices often fail to deliver the required amount of power, so innovative power-combining schemes are still needed. A study of phased arrays driven by individual active solid-state devices has led to a number of interesting and potentially discoveries. It was found that the phases of a number of oscillators, if coupled together properly, can be controlled by means of only one master source and phase shifter. In addition to this experimental demonstration, power combing of planar oscillators in a quasioptical cavity was demonstrated and several effects of coupled oscillators were explored. Finally, the potential of resonant-tunnelling-diode oscillators as self-oscillating mixers was investigated. Keywords: Injection locking; Quasioptics; Power combining; Phased arrays; Coupled oscillators.
