Coaxial To Stripline Spacer

Phased match spacers are described in the publication "Phased Matched Electrical Spacer", P. L. Clouser et al, IBM Technical Disclosure Bulletin, Vol. 16, No. 11, April 1974, pp. 3823-3824. Heretofore, these spacers were used for coaxial-to-coaxial applications.

These spacers have now been found useful for phase matching in coaxial-to- microstrip applications. For example, spacer 10 is concentrically mounted about the conductor pin 11 of a female coaxial connector 12. Thereafter, the protruding part of pin 11 is solder-connected to the printed-circuit conductor 13, which is part of a microstrip substrate of the stripline type. Accordingly, the substrate includes a dielectric layer 14 and conductive ground plane 15. The assembly 13 - 15 is part of a hybrid microstrip circuit (not shown) which is enclosed in partially- shown chassis box 16. Plane 15 is soldered to the inside bottom of box 16 via solder layer S.

Additional connectors (not shown) similar to connector 12 are mounted to box 16 and connected to the microstrip circuit. The connectors are arrayed in predetermined pairs and a spacer 10 is associated with one of the connectors of the pair to effect the phase matching between the connectors of the particular pair. Member 17 is a radiation absorber affixed to the double-layer cover 18 of box 16. A layer of hermetic sealant 19 encapsulates the cover 18 to the sides of box 16.

Preferably, the spacer 10 is mounted internally with resp...
