Qorvo's TQM6M4068 is an advanced dual-band broadband transmit module designed for GSM850 / 900 / DCS / PCS mobile handset applications and provides full RF transmit functionality in a size of only 30 mm². The GSM850 / 900 and DCS / PCS power amplifier blocks, including power control, are combined with a low insertion loss dual-band pHEMT switch, Tx harmonics filtering, integrated switch decoder, two receive ports and ESD protection. This architecture eliminates the need for any power amplifier-to-switch design effort for phone designers. Both 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 have no need for an external reference voltage. With excellent efficiency performance in each band, the power amplifier and switch module contributes to overall talk-time targets in next generation mobile handset designs.
