Diy Ldmos Hf Amplifier. Ldmos Hf Amplifier Schematic A600 linear HF VHF LDMOS amplifier project using 2x MRF300 Amplifier Development I considered the different kits and parts that were available online for the LDMOS amplifiers and settled on the kit parts from Jim Klitzing, W6PQL
10W Class A LDMOS Amplifier 1.854Mhz 50v — VKAMPS from www.vk-amps.com
So after the release of the new LDMOS devices which seemed to be more robust i decided to start another project with the BLF188XR ldmos 600W is about 173Vrms, even with high SWR it's hard to reach 300V and the SWR protection will shut down the amplifier.

600W broadband HF/6m amplifier using affordable LDMOS devices QRPblog Amplifier, Broadband, 600w. I have reworked the output a bit since the article, lost some efficiency and P1dB at 1.8MHz and harmonics look worse now (LPF will solve that) but 3.5 and 7MHz are better and 50MHz is better as well; I expect it to be usable on 70MHz too now. Hello and welcome to the site! I'm putting this site online today, Jan 1, 2018 to be a place to exchange ideas primarily on designing, building and testing LDMOS RF amplifiers, power supplies, LPFs, and just about anything.
