Product data sheet
1. Product profile
1.1 General description
A 300 W LDMOS RF power transistor for broadcast transmitter applications and industrial
applications. The transistor can deliver 300 W broadband over the full UHF band from
470 MHz to 860 MHz. The excellent ruggedness and broadband performance of this
device makes it ideal for digital transmitter applications.
