    Sounds like he's saying it's a 'common positive' system as opposed to 'common negative' to me but ask for detailed advice with schematics to clarify. Is it possible that the company originally...

    Now you have me doubting my memory but I was fairly certain it is a Gunn diode. The circuit (microwave leakage detector) was from a magazine (probably EA or ETI) way back in the 80s and I purchased...

    Sounds like an improvement on the Gunn diode which was invented in the 60's. I made a microwave leakage detector using one of them (Gunn) over 30 years ago and it still works fine over a broad range...
