CDMA Cell 3x3 Power Amplifier Module

(824-849 MHz)

Data Sheet

Description

The WS1103 is a CDMA(Code Division Multiple Access)

power amplifier module designed for handsets operat-

ing in the 824-849 MHz bandwidth.

The WS1103 features CoolPAM circuit technology that

offers state-of-the-art reliability, temperature stability

and ruggedness.

Digital mode control of CoolPAM reduces current

consumption, which enables extended talk time of

mobile devices.

The WS1103 meets stringent CDMA linearity

requirements to and beyond 28 dBm output power. The

3 mm x 3 mm form factor 8-pin surface mount package is

self contained, incorporating 50 ohm input and output

matching networks.
