A K-band monolithic CPW upconverter utilizing a source mixing concept

Abstract

This paper is concerned with the design and performance of a CPW upconverter MMIC for K-band wireless system applications. The upconverter consists of an FET as a "3-port" mixing element, IF, LO, and RF matching networks, and an output filter. Including a 3 dB pass-band insertion loss of the filter, the upconverter exhibits a maximum conversion gain of -6 dB with a port-to-port isolation better than 20 dB.<>
