Helios Polar Loop DigRF EDGE RF Subsystem Family TM TM Description Skyworks HeliosTM Polar LoopTM DigRF EDGE Subsystem combines a direct conversion transceiver and a Power Amplifier (PA) with controller, TR switch and coupler into a dual-chip radio solution that saves significant space, cost, and design cycle time while providing improved performance. It is designed to directly connect to digital baseband device via DigRF interface. All of the necessary RF components needed to build a quad-band, multi-standard handset have been incorporated into the Helios Polar Loop Radio. The highly integrated subsystem includes Skyworks SKY74200 SKY74200 DigRF transceiver and SKY77520 SKY77520 TR Front-end module. Robust and easy-to-implement Polar LoopTM technology Applications · EDGE-based wireless data services · GSM850 GSM850, EGSM900 EGSM900, DCS1800 DCS1800, and PCS1900 PCS1900 handsets · GPRS handsets and modules Features · Polar LoopTM transmit modulation architecture At the heart of the RF subsystem is Skyworks advanced Polar Loop transmit modulation architecture. This unique architecture enables the radio to transmit both constant as well as nonconstant envelope signals through the same transmit path to minimize the number of external components required to build a mobile handset. This significantly reduces the complexity, size, cost, and power requirements of next-generation Enhanced Data for GSM Evolution (EDGE) platforms. The entire RF subsystem fits into a 210 mm2 area. The SKY74200 SKY74200 is based on Skyworks industry-leading, single-chip direct conversion transceiver technology. This device consists of a direct conversion receiver, a transmitter with integrated Voltage Controlled Oscillators (VCOs), low dropout regulators and a fully integrated fractional-N synthesizer. Together with the SKY77520 SKY77520 TR FEM, a seamless closed-loop transmit system is formed. The SKY74200 SKY74200 is available in a 64-pin, 7 x 11 x 1.2 mm Multi-Chip Module (MCM) package. The SKY77520 SKY77520 TR FEM incorporates a GSM850/900 GSM850/900 block, a DCS1800/PCS1900 DCS1800/PCS1900 block, impedancematching circuitry for 50 input and output, an integrated coupler, a T/R switch, and a PA control block. The SKY77520 SKY77520 is fabricated using GaAs technology and is available in a 28-pin, 8 x 8 x 1.5 MCM package. · Integrated noise filtering; no pre-PA filters required · Closed loop phase and amplitude modulation (GMSK, 3/8 -PSK) via control of nonlinear GSM PA · PA inside control loop provides excellent EVM and phase error performance · Direct conversion receiver · Direct connection to battery · DigRF compatible interface · Compact real estate of 210 mm2 PB Skyworks offers lead (Pb)-free "environmentally friendly" packaging that is RoHS compliant (European Parliament for the Restriction of Hazardous Substances).
