WS1403 Overview
The WS1403 is a CDMA Personal munication Service (PCS) Power Amplifier (PA), designed for handsets operating in the 1850~1910 MHz bandwidth. Digital mode control of CoolPAM reduces current consumption, which enables extended talk time of mobile devices. The WS1403 meets stringent CDMA linearity requirements to and beyond 28 dBm output power.
