WS1105
CDMA Cell 3x3 Power Amplifier Module
(824-849 MHz)
Data Sheet
Description
The WS1105 is a CDMA(Code Division Multiple Access)
power amplifier module designed for handsets operating
in the 824-849MHz bandwidth.
The WS1105 features CoolPAM circuit technology that
offers state-of-the-art reliability, temperature stability and
ruggedness.
Digital mode control of CoolPAM reduces current con-
sumption, which enables extended talk time of mobile
devices.
The WS1105 meets stringent CDMA linearity requirements
to and beyond 28dBm output power. The 3mmx3mm form
factor 8-pin surface mount package is self contained, incor-
porating 50ohm input and output matching networks.
