Freescale Semiconductor has unveiled what it touts as the industry's smallest 3G multi-band form factor RF subsystem for handset design.

This solution combines Freescale's EDGE and UMTS technologies into a single, integrated package, enabling dramatic board and cost savings. Significantly reducing time to first call, said Freescale, the new RF subsystem provides the world's simplest programming model for fast, easy implementation and is the first to incorporate an open standard digital interface.

"Our continued focus on delivering robust cellular solutions for our customers is represented clearly with the debut of this subsystem," said Klaus Buehring, vice president and general manager of Freescale's radio products division. "With our highly integrated 3G offering, our customers can deliver the multi-band/multi-mode functionality required in today's advanced handsets. Additionally, we have dramatically simplified layer-one programming, accelerating the time to market for 3G design."

The RFX300-30 subsystem features a single integrated package that supports both multi-mode/multi-band UMTS and EDGE networks. With up to 13 bands supported, the RFX300-30 offers the broadest multi-band support in the smallest form-factor solution for handset manufacturers today. Processed in 90nm CMOS technology, this RF subsystem delivers four-band GSM/EDGE support, nine-band UMTS support, HSDPA support up to 7.2Mbps and HSUPA support up to 5.76Mbps.

The RFX300-30 subsystem combines the analogue base band, RF transmitter, RF receiver, power amplifier and power control and many traditionally passive components into two packages. Specifically, the RFX300-30 consists of Freescale's MMM7210 UMTS/EDGE transceiver and the MMM6038 EDGE power amplifier. The MMM7210 transceiver combines quad-band GSM/EDGE functionality with up to four of nine UMTS bands, providing support for up to eight total bands at any given time.

The RFX300-30 EDGE RF subsystem is already sampling with production slated for Q4 2007.
