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.
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 50Ω matching networks for
both RF input and output
• CDMA 95A/B, CDMA2000-1X/EVDO
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.
Applications
• Digital Cellular (CDMA)
• Analog Cellular (AMPS)
