THere are a pair of waveguide to waveguide transitions in WR-28 waveguide (26-40 GHz): One is WR-28 Square flange to round flange adapter (very useful but I have plenty for my work) and the second is a WR-28 square flange to low impedance (like to match into a diode junction) taper, originally from a waveguide detector made by HP. Experimenters item, have fun! Please see my other items for more RF goodies and weird stuff.
