Enhanced POLARIS Transceiver Provides Customers Two Receiver Options:
-- RF2710 Receiver Enables Quad-Band Operation

-- RF2716 Receiver Enables Quad-Band Operation And Direct Conversion Mode Supporting E-GPRS Receive Capability


RF Micro Devices, Inc. (Nasdaq: RFMD), a leading provider of proprietary radio frequency integrated circuits (RFICs) for wireless communications applications, today introduced an enhanced POLARIS(TM) TOTAL RADIO(TM) transceiver with quad-band and direct conversion capabilities.

The POLARIS TOTAL RADIO solution is a highly integrated radio transceiver for GSM and GPRS (General Packet Radio Service) The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS added a packet-switched channel to GSM, which uses dedicated, circuit-switched channels for voice conversations.  applications. The chipset performs all functions associated with the RF section of a handset and provides handset manufacturers the benefits of reduced component count, flexible baseband interfaces and lower cost of implementation.

The POLARIS transceiver is comprised of the RF6001 mixed-signal processor, the RF3133 power amplifier module with integrated power control and either of two new receivers - the RF2710 or RF2716. Both the RF2710 and RF2716 add quad-band functionality to the POLARIS transceiver; the RF2716 also offers a direct conversion mode, supporting E-GPRS receive capability.

"By introducing both quad-band and direct conversion capability to the POLARIS transceiver, we are further demonstrating our commitment to providing customers best-in-class complete radio solutions at an affordable price," said Brent Wilkins, senior marketing manager for GSM, GPRS and E-GPRS transceivers at RF Micro Devices. "By offering a true quad-band radio solution, RFMD is providing customers the flexibility to develop a single platform that can be manufactured as a dual-, triple- or quad-band handset, minimizing their engineering effort, time-to-market and development cost."

The quad-band POLARIS transceiver supports the U.S. cellular (850 MHz), GSM (900 MHz), DCS (1) See also DSC.

The POLARIS transceiver exceeds all European Telecommunications Standards Institute (body) European Telecommunications Standards Institute - (ETSI) A European version of the ITU-T(?).  (ETSI (European Telecommunications Standards Institute, Sophia Antipolis technical park, Nice, France, www.etsi.org) A non-profit membership organization founded in 1988, dedicated to standardizing information and communication technologies (ICT) throughout Europe. ) specification requirements and features enhanced receiver sensitivity, as well as the ability to handle EDGE modulated signals. Driven by high levels of integration in both the transmit and receive functions, the POLARIS transceiver significantly reduces the number of components required to implement a complete GSM/GPRS radio. All VCOs, associated loop filters and many of the power supply bypass capacitors are integrated on silicon, significantly reducing the complete radio component count. The POLARIS transceiver offers both very low intermediate frequency and direct conversion modes of operation, eliminating all IF SAW filters. The transceiver includes a fractional-N-based digital modulator for reduced power consumption. The chipset is compatible with all major baseband devices and also provides selectable digital baseband interfaces on both receive and transmit paths enabling direct interface to emerging digital baseband products.

Samples of fully assembled RF system boards of the quad-band POLARIS TOTAL RADIO transceiver are available now. The transceiver chip set is priced at $8.50 in quantities of 10,000 units.
