General Description
The advanced dual-band (Broadband Tx) Transmit Module
designed for WCDMA/GSM 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 switch, Tx harmonics filtering, integrated
switch decoder, two Rx ports, two TRx ports, and ESD
protection. This architecture eliminates the need for any PA-
to-switch design effort for phone designers. Up to two bands
of WCDMA or LTE operation is supported by TRx ports and
both Tx and TRx ports are frequency independent, allowing
flexible routing to the transceiver. The QUANTUM Tx™
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.
