PRODUCT DESCRIPTION
WS1111
Power Amplifier Module for CDMA/AMPS(824-849MHz)
Power Amplifier Module for CDMA/AMPS(824-849MHz)
The WS1111 is a CDMA(Code Division Multiple Access) and AMPS(Advanced Mobile Phone Service)
power amplifier module designed for handsets operating in the 824-849MHz bandwidth. The WS1111
is manufactured on an advanced InGaP HBT(Hetero-junction Bipolar Transistor) MMIC(Microwave
Monolithic Integrated Circuit) technology offering state-of-the-art reliability, temperature stability and
ruggedness.
The WS1111 meets stringent CDMA linearity requirements to and beyond 28dBm output power.
The 4mmx4mm form factor 10-pin surface mount package is self contained, incorporating 50ohm input
and output matching networks.
General Features
- 2.0um InGaP HBT Technology
- Good Linearity
- High Efficiency
- 10-pin Surface Mounting Package(4mmx4mmx1.4mm)
- 50ohm Input and Output Matching
- CDMA 95A/B, CDMA2000-1X/EVDO
Applications
- Digital Cellular(CDMA)
- Analog Cellular(AMPS)

No damage assuming only one parameter is set at limit at a time with all other parameters
set at or below nominal value.
High(2.0V – 3.0V), Low(0.0V – 0.2V)
To change between High Power Mode and Low Power Mode, switch Vcont accordingly
In order to shut down the module, turn off Vcont and Vref accordingly
