A 690 GHz receiver was built up by mounting a 690 GHz mixer element in an existing open structure mixer and by upgrading a solid state oscillator used around 345 GHz previously to the 660 to 700 GHz range. A double sideband noise temperature <500 K was accomplished and verified by a laboratory measurement of the 12CO (6-5) molecular line at 691.5 GHz. The mixer is operated at a bath temperature <2.5 K. A particular feature of this receiver is the use of one single SIS contact of submicron dimension. Its production and production and specific merits are addressed.
