PXAE263708NB

Thermally-Enhanced High Power RF LDMOS FET

400 W (P3dB), 28 V, 2620 – 2690 MHz

Description

The PXAE263708NB is a 400-watt (P3dB) LDMOS FET intended for use

in multi-standard cellular power amplifier applications in the 2620 to

2690 MHz frequency band. Features include input and output matching,

high gain and a thermally-enhanced package with earless flange.

Manufactured with Wolfspeed's advanced LDMOS process, this device

provides excellent thermal performance and superior reliability.
