General Description

Pin Out & Assignments

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

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

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.
