Development of MMIC Schottky Diode Mixers For Space-Qualified Applications In The Tera-Hertz Range

In a first part we will discuss the basic principle of mixing operation of the Schottky contact and limitations at Terahertz frequencies related to temperature of operation, material and fabrication parameters. In a second part we will address the space qualification and status of a 1200 GHz mixer and its local oscillator (made at LERMA-C2N) to fulfill the requirement of the Submillimeter Wave Instrument (SWI) JUpiter ICy Moons Explorer (JUICE) mission.
