First Gen9HV LDMOS 140 Watt RF PA transistor from Ampleon

Designed for UHF broadcast applications, Ampleon has introduced BLF989 – an RF power transistor. They will support DVBT and UHF analog TV. Using Ampleon’s latest Gen9HV high voltage LDMOS process, this 140 Watt (average – 700 Watt peak) transistor, the first broadcast device to use this process technology, offers a high operating efficiency of typically > 34% (Class AB) and is available in a ceramic SOT539 package format either with or without mounting ears.

The Gen9HV process used for the BLF989 builds on Ampleon’s industry-respected technology leadership with its broadcast Gen6HV portfolio further enhancing efficiency, gain and ruggedness specifications. The BLF989 is the first in a portfolio of soon to be released Gen9HV products specially designed for broadcast applications.

Featuring best-in-class ruggedness of > 40:1 the BLF989 also offers excellent operating stability and product consistency characteristics, this aiding the whole design-in and production processes for RF power equipment manufacturers. Capable of operating in the UHF range of 400 to 860 MHz, the transistor has a high gain, > 21 dB at Paverage, and optimal gain flatness across the frequency range.   For more…
