Abstract: A power combiner/power divider has a disk shaped housing cavity and a housing of electrically conductive material, such as metal. A junction pin is positioned centrally in the power combiner/divider. Additional ports are positioned radially along the periphery of the disk shaped portion. Tapered waveguides may extend from the radially positioned ports to the centrally positioned junction pin. A hollow radial cavity provided in the cavity holds a dielectric insert that may have tapering extensions radiating from a central ring. The ring surrounds the centrally positioned port.

Abstract: An electro-magnetic device assembly constituted of an electro-magnetic device; a chassis arranged to sink heat; at least one thermally conductive material in thermal communication with the electro-magnetic device and with the chassis; and at least one mechanically isolating material in contact with the thermally conductive material and with the chassis, the at least one mechanically isolating material arranged to dampen the transmission of vibrations experienced by the chassis, in the direction of the magnetic field of the electro-magnetic device, to the electro-magnetic device.

Abstract: A circuit structure may include first and second transmission lines, each with a center conductor extending along or between one or more spaced-apart conducting surfaces. A conducting surface, such as a ground, reference, or signal-return plane, of the first transmission line may have an orientation that is transverse to the orientation of a conducting surface of the second transmission line. Each of the conducting surfaces of the first transmission line may contact one or more of the conducting surfaces of the second transmission line. In some examples, one or both of the transmission lines are slablines, and in some examples, the contacting edges or edges adjacent the contacting edges of the respective conductive surfaces are curved.
