GTRB424908FC/1

Thermally-Enhanced High Power RF GaN on SiC HEMT

450 W, 48 V, 3700 – 4000 MHz

Description

The GTRB424908FC/1 is a 450-watt (P_3dB) GaN on SiC high electron

mobility transistor (HEMT) designed for use in multi-standard

cellular power ampliﬁer applications. It features high eﬀiciency, and

a thermally-enhanced package with earless ﬂange.
