We report on the breakdown of IF power for certain bias voltages for single-diode Schottky mixers at THz frequencies. This dramatic loss of IF power is due to an increase of conversion loss and is governed by intrinsic and external parameters. Based on an analytical approach utilising small signal analysis, it is possible to explain the depth of the breakdown and to estimate the voltage where the breakdown occurs. Measurements for 2nd harmonic mixers show good agreement with analytical predictions.
