Abstract
An RF interconnect is incorporated in RF module packages for direct attachment onto a multi-layer PWB using compressible center conductor (fuzz button) interconnects. The module has circuitry operating at microwave frequencies. The module package includes a metal housing including a metal bottom wall structure. The module includes a plurality of RF interconnects, which provide RF interconnection between the package and the PWB. Each interconnect includes a feedthrough center pin protruding through an opening formed in the metal bottom wall, with isolation provided by a dielectric feedthrough insulator. The center pin is surrounded with a ring of shield pins attached to the external surface of the bottom wall of the module housing. The pins are insertable in holes formed in the PWB, and make contact with fuzz button interconnects disposed in the holes. Circuitry connects the fuzz button interconnects to appropriate levels of the PWB for grounding and RF signal conduction.
