Data Sheet
Description
The WS1403 is a CDMA Personal Communication 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. The 3 mm x 3 mm form factor 8-pin surface mount package is self contained, incorporating 50 ohm input and output matching networks.
Features
Excellent linearity Low quiescent current High efficiency PAE at 28 dBm: 39.8% PAE at 17 dBm: 22.3% 8-pin surface mounting package 3 mm x 3 mm x 1.0 mm Internal 50 ohm matching networks for both RF input and output RoHS compliant
Applications
Digital CDMA PCS Wireless Local loop
