General Description
The advanced Quad-Band (Broadband Tx) Transmit Module
designed for WCDMA/GSM mobile handset applications
provides full RF transmit functionality in a size of only
30 mm
2
. 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, four TRx ports, and ESD protection.
This architecture eliminates the need for any PA-to-switch
design effort for phone designers. Up to four 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
TM
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.
