摘要

A fully integrated Si-bipolar IF-receiver and IF-transmitter with on-chip synthesizer for use in third-generation W-CDMA mobiles is introduced. Both devices incorporate an on-chip IF-synthesizer with on-chip VCO tuning and tank as well as fifth order baseband filters and comply with ARIB W-CDMA and UMTS standards. The devices are mounted in a small outline, 32 pin, leadless surface mount package.
