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.

Claims

1. In a microwave frequency network analyzer having a plurality of individual modules, assembled within a housing, at least some of said modules including microwave components, all of said modules including non-microwave components operating at ratio frequencies lower than microwave frequencies, each of said modules having a plurality of connectors at one surface thereof for conveying signals to and/or from said microwave components and said non-microwave components;

a distribution bar for receiving said plurality of connectors on each of said modules and for use in conveying said signals to, from and between said individual modules, said distribution bar comprising;

an elongated bar of insulating material mounted in said housing at a location against which is placed that surface of each of said modules having said connectors when said modules are in operative position within said housing, a plurality of microwave conduit connectors each mounted within said bar for conducting microwave energy therethrough and receiving said connectors on said modules associated with microwave signals, each of said connectors including oppositely located first and second conduit mateable members, said first conduit mateable member being accessible from within said housing and positioned for releaseable connection to one of said connectors mounted in the module positioned adjacent thereto and associated with a microwave component contained therein, said second conduit mateable member being accessible from outside of said housing, said bar being formed from an insulative material which electrically isolates each of said connectors carrying microwave energy from adjacent connectors to prevent the microwave energy from interfering with signals carrried by said adjacent connectors; and

a plurality of microwave transmitting conduits which are each formed with two opposing ends that can each be releasably connected to selected ones of said second conduit mateable members, whereby microwave energy is transmitted between selected ones of said modules received by said bar and connected to the associated first conduit mateable member.

2. The device of claim 1 wherein each of said connectors is mounted in said bar to ensure alignment of said first conduit mateable members with a respective one of said connectors at said surface of said module.

3. The device of claim 2 wherein each connector is mounted in an aperture formed in said bar, which aperture includes an end positioned about said first conduit mateable member which is formed with a surface upon which said respective module connector bears and is directed into mating engagement with said first conduit mateable member, and wherein said module connector is resiliently mounted on said module surface for lateral movement, whereby said module connector laterally moves as it travels across said aperture surface to allow the same to mate with said first conduit mateable member.

4. The device of claim 3 wherein said aperture surface is an inwardly converging conical surface.
