This paper reviews recent work on multifunctional integration for high frequency applications using HEMT technology. The following topics will be discussed: combination of different circuit functions for complex millimeter-wave ICs, monolithic integration of analog and digital functions. integrated microwave and digital functions, integration of optical and electronical components in OEICs. In the first pail, interconnection techniques for multifunctional integration will be described. Due to the inherent advantages, we will focus on coplanar waveguides (CPW). The next section is dedicated to active device issues which are relevant for multifunctional integration. In the following sections we will present different examples for multifunctional circuits which comprise 77 GHz automotive radar. 15 GHz and 34 GHz phase locked loop oscillators, a 35 GHz phase shifter, and high speed optoelectronic receiver circuits based on MSM and PIN photodetectors.
