Abstract

A prototype design of a 2.7 V, 14.5 mA SiGe direct-conversion receiver IC for use in 3G WCDMA mobile cellular systems has been completed and measured. The design includes a bypassable LNA, a quadrature downconverter, and variable gain baseband amplifiers integrated on chip. The static sensitivity performance of the receiver IC is characterized using a software baseband processor to compute link bit-error rate.
