Abstract:
1. A transition block configured to be surface mount attached to a surface of a circuit board and effective to couple a microwave radio frequency signal between a microstrip arranged on the surface and a waveguide oriented perpendicular to the surface, said transition block comprising: a top metal layer; a first dielectric layer underlying the top metal layer; a middle metal layer underlying the first dielectric layer, wherein the middle metal layer defines a probe extending from a first location proximate to an edge of the transition block to a second location proximate to a central region of the transition block; a second dielectric layer underlying the middle metal layer; a bottom metal layer underlying the second dielectric layer, wherein the bottom metal layer defines a first opening aligned with the first location and a second opening aligned with the central region; an electrical connection means that forms an electrical connection from the first opening to the first location, and makes electrical contact therewith the probe; and a plurality of thru-vias arranged about the central region and in electrical contact with the top metal layer and the bottom metal layer.
