Coplanar High Performance MMICs in MHEMT and PHEMT Technology for Applications up to 100 GHz

摘要

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.
