WS1111

4 x 4 Power Amplifier Module

for CDMA/AMPS (824 – 849 MHz)

Data Sheet

Description

The WS1111 is a CDMA (Code Division Multiple

Access) and AMPS (advance mobile phone service)

Power Amplifier (PA), designed for handsets operat-

ing in the 824~849 MHz bandwidth.

The WS1111 features CoolPAM circuit technology that

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

ity and ruggedness.

Digital mode control of CoolPAM reduces current

consumption, which enables extended talk time of

mobile devices.

The WS1111 meets stringent CDMA linearity require-

ments to and beyond 28 dBm output power. The 4 mm

x 4 mm form factor 10-pin surface mount package is

self contained, incorporating 50ohm input and out-

put matching networks.

Features

• Good linearity

• High efficiency:

41% at Pout = 28 dBm

18% at Pout = 16 dBm

• 10-pin surface mounting package

(4 mm x 4 mm x 1.4 mm)

• Internal 50

Ω matching networks for

both RF input and output

• CDMA 95A/B, CDMA2000-1X/EVDO

Applications

• Digital Cellular (CDMA)

• Analog Cellular (AMPS)
