Cellular phones in emerging markets have continued to grow with multimedia features such as MP3 playback, video encode and decode, high-resolution cameras and web browsing. To efficiently support multimedia functionalities, highperformance modems are required. There is also a strong demand to reduce the cellular phone PCB footprint, and to enable integration of peripheral devices such as Bluetooth and Wireless LAN. Previously reported SoC or SiP solutions have integrated a GPRS/EDGE radio with modem and limited multimedia capabilities [1–4]. This paper presents a multimode UMTS/GSM RF transceiver integrated with a digital baseband having advanced multimedia functionalities. The SoC, designed in 65nm digital CMOS, supports quad-band GSM/GPRS/EDGE (3GPP R4, Class 12) and tri-band UMTS/WCDMA (3GPP R99, R5 cat 5/6), including band 1–2–4–5–6–8–9–10.
