Abstract

A fully integrated SAW-less direct conversion CDMA receiver with single-ended LNA and modified single-balanced passive mixer is manufactured in a 65 nm digital CMOS process. The measured receiver gain at 1.96 GHz was 37 dB, NF was 3 dB, IIP2 was +62 dBm, and cross-modulation triple beat (TB) was 65 dB.
