Abstract :
A SAW-less (in Rx and Tx) tri-band (2 high, 1 low) WCDMA/HSPA transceiver IC is presented. An Rx IIP2 enhancement technique achieves IIP2 of +55 dBm without production calibration or special processing steps. Integration of an on-chip DC-DC converter simplifies RF subsystem eBOM and reduces current drain from battery to 40 mA/65 mA in Rx/Tx mode, respectively.
