Abstract

This paper reports on the design of a coplanar up-converter from C- to V-band on GaAs. An optimum conversion gain (62-64 GHz: G/sub c/>4 dB) has been achieved from a nonlinear optimisation, utilising a modified Tajima model for the PM-HFETs and an accurate library for the coplanar elements integrated into the CAD tool Libra. Due to the use of coplanar lumped elements, a very compact circuit size of 2.1 mm/sup 2/ has been obtained. The evaluation of the circuit demonstrates the excellent agreement of the linear and nonlinear measured and simulated mixer behaviour up to 64 GHz.
