Abstract
Monolithic millimeter-wave amplifiers for the frequency ranges of 60 a nd 77 GHz on an InP substrates are presented. Both circuits use lattic e-matched InAlAs / InGaAs / InP HEMTs with triangular-shaped gates and a gate length of L(G) = 0.25 mu m. Coplanar waveguides and lumped ele ments are used for the matching and biasing networks. The circuits are fully passivated and contain common ports for the gate and the drain bins. A gain of 15 dB and input and output matching better than -8 dB were achieved for the 60- and 77-GHz amplifiers, respectively. (C) 199 6 John Wiley & Sons, Inc.
