Product Description
The advanced quad-band Transmit Module designed for mobile handset
applications provides full RF transmit functionality in a size of only 36 mm2.
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 talk-
time targets of next generation mobile handset designs.
