Abstract: An electronic device which includes multiple components separately housed in electromagnetically isolating modular units, which units are interchangeably and detachably mounted in a frame. The frame and modular units are formed to releasably connect the various components to sources of electrical and/or microwave energy.

Abstract: A microwave device including various electromagnetically isolated components assembled with a microwave distribution bar in a single housing. A microwave distribution bar is formed to distribute microwave energy to those individual components which are selectively connected thereto.

Abstract: A modular electronic shielding assembly having a housing in which a ground plane platform is held. The housing is formed from a conductive material which provides for electromagnetic isolation. The ground plane platform also provides for electromagnetic isolation by having disposed on one side thereof a conductive layer. This ground plane platform separates the housing into two electromagnetically isolated compartments. The ground plane platform has electronic circuitry formed upon that surface opposite the conductive layer, which circuitry is isolated from the microwave components by one of two techniques. The first involves mounting the components to the opposite surface of the platform which carries the conductive layer, or by forming the components on one side of a daughterboard with the opposite side bearing a conductive layer. The daughterboard is mounted on that platform surface bearing the circuitry with the daughterboard conductive surface facing the circuitry.
