Abstract :
This paper presents the design, fabrication and measurements of a fourth-harmonic Schottky diode mixer working at sub-millimeter frequencies, in particular at an RF frequency of 440 GHz. Measured DSB noise temperature of 7900 K and conversion loss of 14 dB have been obtained. This configuration offers an alternative solution which simplifies the LO signal generation. It can find an application in imaging systems, where arrays of detectors need to be simultaneously fed by the same LO.
