Abstract
This paper describes one of the first dual PCS- and CEL-band CDMA receivers that includes LNAs and VCOs on a single die. The PCS-band LNA achieves a noise figure (NF) of 1.5 dB and IP3 of /437.5 dBm at 16-dB gain. The PCS demodulating mixer achieves an NF of 5 dB, IP3 of /435 dBm and uncalibrated IP2 of /4360 dBm. The PCS VCO is capable of 134 dBc/Hz phase noise at 3.9 GHz and 1.25-MHz offset. A copper BiCMOS process was chosen for both performance and cost benefits, compared with lower geometry CMOS.
