Method and apparatus for the interconnection of radio frequency (RF) monolithic microwave integrated circuits

摘要

A coaxial-to-coplanar waveguide connector is used for interconnecting stripline compatible devices utilizing coaxial cable. The connector is formed at the end of a length of coaxial cable embedded within a circuit board. The connector generally has a substantially semi- circular connection section. The connection section includes a conductor partly surrounded by an electrically insulative dielectric which is partly surrounded by a shield. An electrically conductive sheet is used to couple the shield to a ground plane of the circuit board. Electrically conductive ribbon is connect the conductor to a stripline compatible device. The coaxial-to-coplanar waveguide connector may be fabricated by coating a dielectric board with an adhesive material and then routing a length of miniature coaxial cable in the adhesive. Conductive material and dielectric material are consecutively laid upon the dielectric cable board. A portion of the board including a section of miniature coaxial cable is milled so as to remove a top portion of the cable. An electrically conductive material is coupled to the coaxial shield in order to connect the shield to a ground plane of the circuit board and the stripline compatible device. Furthermore, an additional electrically conductive ribbon is operatively connected from the conductor to the stripline compatible device.
