A 50 nm-gate lattice-matched InAlAs/InGaAs HEMT with the cutoff frequency of 362 GHz was developed. A K-band power amplifier module achieved the output power of 33.5 dBm at 24 GHz. A miniature and broadband p-HEMT LNA MMIC exhibited the gain of 14.5 dB and the noise figure of 1.7 dB at 26 GHz. A set of 76 GHz fully MMIC chips based on the 0.15 ¿m-gate p-HEMT process was developed for the car radar systems. Low-price, small-size and easily usable 60 GHz modules are expected by mm-wave home-link use.
