PXAC182002FC
Thermally-Enhanced High Power RF LDMOS FET
180 W, 28 V, 1805 – 1880 MHz
Description
The PXAC182002FC is a 180-watt LDMOS FET with an asymmetri-
cal design intended for use in multi-standard cellular power amplifier
applications in the 1805 to 1880 MHz frequency band. Features
include dual-path design, input and output matching, high gain and
thermally-enhanced package with earless flanges. Manufactured
with Wolfspeed's advanced LDMOS process, this device provides
excellent thermal performance and superior reliability.
