The WS1103 is a CDMA(Code Division Multiple Access)
power amplifer module designed for handsets operat-
ing in the 824-849 MHz bandwidth.
The WS1103 features CoolPAM circuit technology that
ofers 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.
