Abstract

In this paper we present coplanar MMICs based on both, metamorphic (MHEMT) and pseudomorphic (PHEMT) high electron mobility transistor technologies. Starting with a modulator-driver MMIC for optical transmission systems, we describe state of the art MMICs like a 94 GHz low-noise amplifier, a 35 GHz and a 60 GHz medium power amplifier and finally we demonstrate the feasibility of a monolithically integrated 94 GHz single-chip FMCW radar sensor.
