Rx3 RX RF Output Product Description The advanced quad-band multimode GSM/EDGE Transmit Module designed for mobile handset applications provides full RF transmit functionality in a size of only 36 mm2. This module has been optimized for high EDGE efficiency and EDGE power class E2 operating while maintaining high GSM/GPRS efficiency. The GSM850/900 and DCS/PCS power amplifier blocks including power control are combined with the low insertion loss quad-band pHEMT switch, Tx harmonics filtering, integrated switch decoder, four receive ports, and full ESD protection. This architecture eliminates the need for any PA-to-switch design effort for phone designers. All four Rx ports are frequency independent and allow flexible routing to the transceiver. Fabricated in high-reliability InGaP HBT / pHEMT technology, the module supports GPRS class 12 operation and provides 50 Ohms input and output impedances at all RF input and output ports. The module control inputs are CMOS compatible and has no need for an external reference voltage. With its excellent efficiency performance in all 4 bands, the power amplifier and switch module contributes to the overall talktime targets of next generation mobile handset designs. Applications * * GSM GPRS/EDGE Handsets and Modems Dual-, Tri-, Quad-band Class 12 Compatible Package Style Preliminary Data Sheet: Subject to change without notice 1 For additional information and latest specifications, see our website: www.triquint.com Revision 2.1, November 29, 2006 |
