The status of lattice-matched high-electron-mobility transistors (HEMTs) and pseudomorphic AlInAs-GaInAs grown on In substrates is reviewed. The best lattice-matched devices with 0.1-μm gate length had a transconductance gm=1080 mS/mm and a unity current gain cutoff frequency fT=178 GHz, whereas similar pseudomorphic HEMTs had gm=1160 mS/mm and fT=210 GHz. Single-stage V-band amplifiers demonstrated 1.3- and 1.5-dB noise figures and 9.5- and 8.0-dB associated gains for the lattice-matched and pseudomorphic HEMTs, respectively. The best performance achieved was a minimum noise figure of Fmin=0.8 dB with a small-signal gain of Ga=8.7 dB
