PXAC243502FV
High Power RF LDMOS Field Effect Transistor
350 W, 28 V, 2300 – 2400 MHz
Description
The PXAC243502FV LDMOS FET is a 350-watt LDMOS FET de-
signed for use in power amplifier applications in the 2300 MHz to
2400 MHz frequency band. Features include an asymmetric design
with high gain and a thermally-enhanced package with earless flange.
Manufactured with Infineon's advanced LDMOS process, this device
provides excellent thermal performance and superior reliability.
