A 94-GHz HEMT (high-electron-mobility transistor) mixer was designed and fabricated using a 0.1- mu m-gate HEMT device and a hybrid microwave integrated circuit. The mixer downconverts the 92-96-GHz RF to a 8-12-GHz IF (intermediate frequency). At 4-dBm LO (local oscillator) drive, the mixer showed 5.8-dB conversion loss, 12.4-dB noise figure, and -3.2-dBm input power at the 1-dB gain compression point. The HEMT mixer is suitable for a 94-GHz missile seeker application where available W-band LO power is extremely low. The HEMT mixer can be monolithically integrated with a HEMT low-noise amplifier to form a low-cost, small-size, and low-weight receiver front end for use in millimeter-wave smart munitions.
