摘要：
This paper presents the design of an integrated CMOS 5.5/2.4GHz dual-band smart-antenna transceiver for WLAN 802.11a/b/g applications. The phase shifter in the transceiver provides a variable 0degrees to 360degrees RF phase shift to each signal path at both bands using a novel integrated phase shifting approach. The transceiver is a typical super-heterodyne architecture. The chip is designed to operate with any off-the-shelf digital baseband chip. It is fabricated in a 0.18mum 60GHz CMOS technology. The chip size is 2000mum x 3000mum. The overall power consumption excluding off-chip power amplifier and IF/basebanid chip is 100mW in receive mode and 90mW in transmit mode, with an acceptable supply voltage range of 1.8 to 3.3V.
