UHF power LDMOS transistor

Rev. 3 — 24 May 2019

Product data sheet

1. Product profile

1.1 General description

A 900 W LDMOS RF power transistor for broadcast Doherty, class-AB transmitter and

industrial applications. The excellent ruggedness of this device makes it ideal for digital

and analog transmitter applications in the frequency range from 400 MHz to 860 MHz.
