Re: #ubitx Power output on 40 / 80 m with high current levels #ubitx
Layout is important, as John has said. I'd suggest a very short source lead soldered directly to the ground plane,toggle quoted messageShow quoted text
keep the drain lead well separated from the other two (Allison suggests clipping the drain lead off and soldering to the tab),
and try adding a 10 ohm resistor in series with the gate.
