A 140 GHz Balanced Mixer for Finline Integrated Circuits

First results of a 140 GHz finline balanced mixer are reported. The mixer is based on the cambination of finline and coplanar line. Schottky-barrier beam-lead diodes are used as mixer diodes. This mixer, together with other finline components under developnent, gives the basis for low-cost 140 GHz integrated finline circuits.
