Freescale Semiconductor introduced a quad-band GSM/GPRS/EDGE RF subsystem that increases talk time for handsets by up to 20% versus previous generations of GPRS handsets. The new subsystem consists of a transceiver and a power amplifier front end module. Combined, these two components provide an antenna-to-bits radio in a board space of less than 250 mm2 — approximately the area of a postage stamp.
Freescale said the solution represents 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 RF integrated circuits for digital cellular terminals. http://www.freescale.com
