I have had the parts and boards for this sitting here for quite some time. After posting all the schematics and board files for everything i had working, i took a few weeks off to chill and regroup. Actually I have been racing F3 in Iracing and having a really good time. So anyway, today i got keen and thought i would assemble this board to see how i went. Other than leaving the DC blocking caps off and having to bodge them in, the board actually worked well. It has been sitting on the bench running for the last 30 mins and its barely gotten warm. Talk about some efficiency in these modern transistors. Signal source is an SI5351a and so square wave in and square wave out. This thing will chooch 5w all day without a problem. I was not sure it would work well, the fets are speced for UHF and I am using them at HF. I have the big brother to this fet and it will do 20w, so when i get brave I will have to see if i can make more power.
