I was doing some measurements and accidentally disconnected supply power with connected power input from driver. So gates got more than negative 0.5v and right gate has died.
Drilling holes in a coper is a pain.
And bigger pain is to cut the thread in it.
MRF9180 amplifier — feeding transistor via balancing choke
Let’s try to add balancing choke to the schematics — feed sources from 4 turn choke for each transistor (8 turns summary) with power connected to the central point.
