Abstract—MMIC (monolithic microwave integrated circuit) chip set was developed for application to wireless PAN. Concretely, cascade type transceiver mixers employing GaAs p-HEMT were fabricated on GaAs substrate. The mixer MMICs showed good RF performances. Concretely, the conversion gain of the receiver mixer was 9.6 dB at a LO input of 8 dBm, and 9.6 ± 1.6 dB at a RF frequency range of 62.5 - 63.5 GHz. The chip size of the receiver mixer was 2.7 mm x 1.35 mm. The conversion gain of the transmitter mixer was 6.5 dB at a LO input of 8.5 dBm, and 6.5 ± 0.25 dB at a IF frequency range of 1.9 - 2.9 GHz. The chip size of the transmitter mixer was 2.7 mm x 1.35 mm. 0.2 μm
