Abstract :
This paper presents a single chip, superhetrodyne receiver IC capable of supporting dual-band, tri-mode handsets. Supported standards include W-CDMA, CDMA (IS-98-C) and AMPS. The receiver consists of multistep gain LNAs, high performance RF mixers with adjustable linearity, a variable gain amplifier, on chip VCO cores, and an IQ downconverter. The IC is fabricated in a 35 GHz f/sub t/ Si BiCMOS process and packaged into a 48 pin 7 mm/spl times/7 mm land grid array (RF-LGA/sup TM/) chipscale package.
