WS1403
CDMA PCS 3x3 Power Amplifier Module
(1850-1910 MHz)
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
