WS1102
3 x 3 Power Amplifier Module for CDMA/AMPS (824–849 MHz)
Data Sheet
Description
Features
The WS1102 is a CDMA (Code Division Multiple ­Access)
and AMPS (Advanced Mobile Phone Service) power
amplifier module designed for handsets operating
in the 824–849 MHz bandwidth. The WS1102
features CoolPAM circuit technology that offers
state-of-the-art reliability, temperature stability and
ruggedness.
The WS1102 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.
• Good linearity
• Excellent efficiency: 40% at Pout = 28 dBm;
19% at Pout = 16 dBm (without a DC/DC converter)
• 8-pin surface mounting package
(3 mm x 3 mm x 1.1 mm)
• Internal 50Ω matching networks for both RF Input
and output
• CDMA 95A/B, CDMA2000-1X/EVDO
Applications
• Digital Cellular (CDMA)
• Analog Cellular (AMPS)
