Designing commercially viable MM-wave modules

Millimeter-wave module manufacturing has become a commercial reality but many challenges related to cost still remain. A practical integration methodology that uses a novel wide-band microstrip-to-rectangular waveguide transition at 77 GHz is presented. EM based tolerance analysis shows that deleterious resonance can cause significant signal degradation. Accurate EM simulations and re-sampling techniques are useful for improved design and cost reduction.
