1.1 General description
1.2 Features and benefits
A 500 W LDMOS RF power transistor for broadcast transmitter applications and industrial
applications. The transistor is optimized for digital applications and can deliver 110 W
average DVB-T broadband over the full UHF band from 470 MHz to 860 MHz. The
excellent ruggedness of this device makes it ideal for digital transmitter applications.
