This paper discusses the techniques developed to design integrated anti-parallel Schottky diode mixers. The use of these techniques has enabled us to efficiently design and build submillimeter wavelength mixers that are not only highly sensitive, but also have enhanced mechanical robustness and large fixed tuned bandwidth. A coaxial probe technique is used with a finite-element analysis program to determine the loop and external embedding impedances of the anti-parallel diode pair. Nonlinear analysis of the diode is performed to examine such issues as mixer sensitivity and LO power requirement. As a design example, a 400 GHz subharmonic mixer with state-of-the- art performance is considered.
