rfD_NP01.jpg" HSPACE="7" ALIGN="RIGHT">Freescale Semiconductor disclosed that they are able to increase talk time for handsets by up to 20 percent versus previous generations of GPRS handsets with the introduction of its quad-band GSM/GPRS/EDGE RF subsystem for world phones.

This new subsystem consists of the MMM6000 transceiver and the MMM6027 power amplifier front end module. Combined, these two components provide an antenna-to-bits radio in a board space of less than 250mm?. According to Kent Heath, director of cellular operations for Freescale's Radio Products Division, they were able to develop the "most advanced and optimized EDGE RF subsystem" using its new power efficient polar architecture.

"This solution is engineered to allow the highest capability for the smallest space and longest talk time at a great savings," Heath added.

The press release further said that the MMM6000 and MMM6027 constitute the world's first digrf compliant radio allowing for maximum flexibility in pairing the RF subsystem with any semiconductor company's baseband. DigRF is a global standard of an efficient physical interconnection between baseband and RFICs for digital cellular terminals, explained Freescale.

System parts
The MMM6000 polar EDGE transceiver provides full DigRF to analog RF functionality in a 9-by-11mm package, eliminating the separate analog baseband required by many other chipsets. According to the company, the transmitter removes costly components, such as filters, which in turn helps to reduce the costs for manufacturers and consumers.

Designed to support the MMM6000 transceiver, the MMM6027 is a member of Freescale's fourth generation front end modules and is housed in an 8-by-8mm package.

Both the MMM6000 and MMM6027 are incorporated into Freescale's Innovative Convergence i.275 platform or can be designed in as a standalone RF subsystem with any baseband. Samples are already available with production targeted for 2Q 2005.
