Functional Block Diagram
Product Description
The advanced dual-band Transmit Module designed for GSM850 / PCS
mobile handset applications provides full RF transmit functionality in a size of
only 36 mm
control are combined with the low insertion loss dual-band pHEMT switch, Tx
harmonics filtering, integrated switch decoder, two receive ports, and full 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 has no need for
an external reference voltage. With its excellent efficiency performance in
both bands, the power amplifier and switch module contributes to the overall
talk-time targets of next generation mobile handset designs.
