A hybrid integrated 89 GHz sub-harmonic mixer based on Schottky diode was proposed for meteorological monitoring radiometer. In this paper, based on the theory of millimeter wave mixing technology, a three-dimensional electromagnetic model of diode is established in the field simulation software, and a W-band 89 GHz sub-harmonic mixer is designed based on the three-dimensional electromagnetic model. The simulation and test results show that when the Local Oscillator (LO) is fixed at 45 GHz, the conversion loss is better than 14 dB from 84 to 94 GHz, and the minimum conversion loss is 9 dB. The measured results are consistent with the simulation results.
