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.
