Is there data showing more dissipated heat with lower output in solid state amplifiers? I have seen similar posts on the SPE Expert list. The following KPA1500 post shows much lower efficiency with lower power but not more lost wattage: I am not an RF amp guru, I am just trying to understand this. http://mailman.qth.net/pipermail/elecraft/2018-August/259502.html

Outside this design point (both high and low), efficiency will fall off and you will find that the amp will run hotter 73, Jack, W6FB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
