WS1105

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 consumption, 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, incorporating 50ohm input and output matching networks.
