Abstract

In this paper a generic mixer test jig for millimeter wave Schottky diode testing is presented. The test jig enables relatively easy changing of the diode under test and thus testing and comparison of different mixer diodes in realistic operating conditions. The diode under test is mounted on a substrate and flexible RF and LO impedance matching is performed with integrated low-loss waveguide EH-tuner. The feasibility of the mixer test jig is tested with a commercial Schottky diode. The measured double side band (DSB) conversion loss is 4.6 dB and the DSB mixer noise temperature 650 K. The test jig is designed for the nominal RF frequency of 183 GHz.
