Abstract
This paper describes a novel single-chip W-band wireless transceiver utilizing a direct mm-wave QPSK modulator. The transceiver was fabricated in a 130 nm SiGe BiCMOS technology and can operate at data rates in excess of 10 Gb/s. The Zero-IF receiver peak gain is 50 dB, the noise figure is 7 dB while the 3-dB IF bandwidth extends over 6 GHz. The differential transmitter achieves a maximum output power of +9 dBm, while the transceiver occupies 1.9 mm times 1.1 mm. The total power consumption, including the 4 times 20 Gb/s PRBS generator, is 1.2 W from 1.5, 2.5 and 3.3 V power supplies.Keywords
