WS1403

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 Order Information Part Number WS1403-TR1 No. of Devices 1,000 100 Container 7” Tape and Reel BULK Functional Block Diagram Vref (1) Vcont (2) WS1403-BLK MMIC BIAS CIRCUIT & CONTROL LOGIC RF INPUT (3) INPUT MATCH DA INTER STAGE MATCH PA OUTPUT MATCH RF OUTPUT (6) MODULE Vcc1 (4) Vcc2 (5) Free Datasheet http://www.datasheet4u.com/ Table 1.
