This product is not recommended for design-in.
The recommended type is: BLF989
UHF power LDMOS transistor
A 900 W LDMOS RF power transistor for broadcast Doherty and class AB transmitter applications. The excellent ruggedness of this device makes it ideal for digital and analog transmitter applications.
This White Paper explains different PA architectures which can be used in today’s UHF Broadcast industry.
In this paper a brief discussion will be given to explain these new Doherty architectures and to help customers finding the best solution for their transmitter. Ampleon’s transistor family BLF8XX can support these Doherty architectures.
