Neil G4DBN@ftg @azonenberg @dlharmon I general, I cheat by not trying to use coax above 24 GHz, but I really should give it a go at 47 GHz one day. I'm thinking in terms of using spatial combiners though, all in waveguide, right from the device outputs. The detailed engineering needed to get excellent matches across coax to CPWG or microstrip is Officially Hard.
