General Description
The advanced dual-band (Broadband Tx) Transmit Module
designed for GSM850/900/DCS/PCS mobile handset
applications 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 PA-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.
