The WS1403 is a CDMA Personal Communication Service
(PCS) Power Amplifer (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. The
3 mm x 3 mm form factor 8-pin surface mount package
is self contained, incorporating 50 ohm input and output
matching networks.
