I have built one 150w amp which was used for several months on 1296 eme. My experience with building other amplifiers using SHF devices at VHF frequencies has shown that many of these dedicated devices will work at lower frequencies. Now i pull it over from it's case to mount it on a new DIY heatsink. Ed, NT2X used this amplifier at VR2EH (Hong Kong) in Oct 2011. It's a hard to find and expensive transistor anymore as is its close cousin the 80 watt MRF-454. datasheet search, datasheets, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes and other semiconductors. Having tested the amplifier into a dummy load it was time to put the amp “on the air” I started with 40Metres and called CQ with 5 watts only. amplifier design. They include plastic, metal. Impedance matching is a fundamental aspect of RF design and testing; the signal reflections caused by mismatched impedances can lead to serious problems.
