The idea of putting together a quick transverter for 47GHz came to me after 2012 RAL. Having come away with an offset dish (thanks Peter), and a WR-28 four port waveguide switch. It was decided to try and put something together in 4 hours, and have it ready for the '76~(th)' August tests. Of course it took 6-7 hours to build, but was finished in time! The other component that I needed had come from ebay - A Honeywell WR-28 mixer, with IF amplifier attached. I had previously removed the IF amp, and was using it as a X2 multiplier 38 / 76GHz. It worked pretty well in that role giving 1.2mW out for 80mW drive. Hopefully it would work well in its original role as a mixer, but at 47GHz.
