Multiple element oscillators utilizing a new power combining technique

Abstract

A method for combining the microwave and millimeter-wave power generated by many two or three terminal devices is presented. This method forms a single resonant structure from many active devices, and therefore the combiner is stable and does not suffer from simultaneous multimode difficulties. The technique produces compact structures and is readily adaptable to monolithic integration. Through an eigenvalue-eigenvector analysis of the structure, multiple device circuit interactions are investigated. The oscillation stability is demonstrated by large-signal analysis of the circuit in the time domain. Experimental results from several power combiners utilizing Gunn diodes are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
