A direct-conversion receiver IC for WCDMA mobile systems.

A prototype design of a 2.7-3.3-V 14.5-mA SiGe direct-conversion receiver IC for use in third-generation wide-band code-division multiple-access (3G WCDMA) mobile cellular systems has been completed and measured. The design includes a bypassable low-noise amplifier (LNA), a quadrature downconverter,...
