My approach, FWIW, to the design of a second stage of a 'bomb-proof'

of two combined using 0degree hybrids and then combined into a push-pull
amplifier would give very good performance, but beware of mixer damage
if you have strong local signals!!

I think we need an Eimac 4CX10,000A  as a mixer in contests, with a 4CX250B in the front end. This reminds me, I need to send you some data sheets. I had forgotten about that but will do it asap.
