Designing circuits for millimeter-Wave applications is a highly specialized and challenging skill. Vishay has made design tools available which simplify the design process, including S-parameters, 3D mechanical models, 3D electromagnetic models, and modelithics models, all of which are compatible with the most commonly used simulation software available. For prototyping, samples and sample kits may also be purchased from the DigiKey website, and characterization boards may also be requested.
