Modeling of commercial millimeter wave Schottky diodes

Abstract

We present a 3-D electromagnetic modeling method for planar Schottky diode based on a field-circuit integrated way. A 3-D EM model of the linear part of a commercial Schottky diode, which is MA46H146 fabricated by MACOM in this paper, is established in HFSS. The linear part of the diode is co-simulated with the non-linear part in ADS. The simulated S parameters agree well with the measured results using TRL calibration. A Q-band frequency doubler is then designed based on this model. We found that the measured output power of the doubler is consistent with the simulated result, which verifies the validity of this model.
