Метка: mrf9180

Just received a few mrf9180 and one mrf9120, decided to finally test it with mrf9120.

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.

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.

Based on mr9120 aliexpress kit.
