EuMW 2018: RF power transistor withstands a VSWR of 65:1
A high power rugged BLF189XRA RF power transistor aimed at broadcast FM radio applications transmitting in the 88 – 108 MHz frequency range was unveiled at European Microwave Week in Madrid (September 25-27). Operating from an industry standard 50V power source the BLF189XRA delivers over 1,600W (CW).
Featuring an operating power efficiency of >82%, the transistor’s “green” credentials help deliver an environmentally-friendly performance and being capable of delivering such power levels from a single SOT539 package reduces the number of RF power transistors required overall.
In addition, for a given output power requirement, reducing the number of PA transistors required keeps the size and costs of a transmitter to a minimum.
The BLF189XRA is an extremely rugged device that can withstand a VSWR of 65:1, conditions which might be encountered in a harsh operating environment or during maintenance routines.
Ampleon’s stable manufacturing production processes aids maintaining high levels of product consistency which coupled with comprehensive application support helps end-equipment manufacturers reduce the time needed to bring their product to market.
