Tranceiver Mixer MMICs Employing Cascode Circuit Structure for Personal Area Network (PAN) Applications
Keywords:
MMIC (monolithic microwave integrated circuit), mixer, PAN (personal area network)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
