Abstract: The paper presents the design, fabrication and measurement of a low-loss fixed tuned 105-130 GHz subharmonically pumped mixer, utilizing planar GaAs Schottky barrier diodes flip-chipped onto a suspended microstrip circuit. The substrate material is 0.127-mm-thick RT/duriod-5880 instead of expensive quartz. The measurement performance of the mixer exhibits a conversion loss below 10 dB over the range of 105-130 GHz, with a fixed local oscillator (LO) frequency of 59 GHz and its power of 5 mW.

Keywords: Terahertz, Schottky diodes, Sub-harmonic mixer.
