TQM6M4003

The advanced quad-band Transmit Module TQM6M4003 designed for mobile handset applications provides full RF transmit  unctionality in a size of only 36 mm2. The GSM850/900 and DCS/PCS power amplifier blocks including power control  re combined with the low insertion loss quad-band pHEMT switch, Tx harmonics filtering, integrated switch decoder,  our receive ports, and full ESD protection. This architecture of TQM6M4003 eliminates the need for any PA-to-switch design effort for  hone designers. All four Rx ports are frequency independent and allow flexible routing to the transceiver. Fabricated  n 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 of TQM6M4003 are CMOS compatible and   s no need for an external reference voltage. With its excellent efficiency performance in all 4 bands, the power  mplifier and switch module TQM6M4003 contributes to the overall talk-time targets of next generation mobile handset designs.
