UHF power LDMOS transistor

Rev. 3 — 17 February 2022

Product data sheet

1. Product profile

1.1 General description

A 1000 W LDMOS RF power transistor for asymmetrical broadcast Doherty transmitter

applications which operates at 180 W DVB-T average power. 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.
