A non-contact type coaxial switch that eliminates all contacts and inner conductors. The switch includes a stator/coax base assembly and a rotor. The stator/coax base assembly is fixed, while the rotor is rotatably mounted to the stator/coax base assembly and eliminates all contacts and inner conductors. The rotor is disposed between bearings, and consists of waveguide paths that couple between selected coax connectors. When the rotor is rotated, different selected coax connectors occur. For other arrangements selected, the rotor can switch between a condition of coax and waveguide outputs. The rotor, between bearings, consists of waveguide paths which couple between selected coax connectors. When the rotor is rotated, a different selected coax connector occurs. For other arrangements selected, the rotor can switch between a combination of coax and waveguide outputs.

The rotor, between bearings, consists of waveguide paths which couple between selected coax connectors. When the rotor is rotated, a different selected coax connector occurs. For other arrangements selected, the rotor can switch between a combination of coax and waveguide outputs. The switch can assume many configurations. For example, a Double-Pole-Double-Throw (DPDT) configuration; a 3 and 4 Way R-Type configuration; a Single-Pole-Multiple-Throw (SPMT) configuration; a T-Switch configuration; and a Multiple-Pole-Multiple-Throw (MPMT) configuration.

A microwave switching device comprises: a switching matrix with M inputs and N outputs comprising at least one surface-mount microwave switch with ohmic contacts with at least one input and at least one output position; a control bus for the one or more microwave switches of the switching matrix; a telemetry bus for the M inputs; a telemetry bus for the N outputs; a bias tee positioned on each input of the switching matrix; and a bias tee positioned on each output of the switching matrix.

A microwave branching switch for selectively interconnecting terminals of a plurality of microwave transmission lines, involving microwave transmission lines with a terminal; a housing in which the terminals are arranged; a switching portion with a junction portion for selectively interconnecting terminals of the microwave transmission lines through selective interconnection. The switching portion is switchable between a first position and a second position; wherein the switching portion with the junction portion is dimensioned and positioned inside the housing in dependence of an arrangement of the microwave transmission lines such that the junction portion interconnects a first group of terminals when the switching portion is in the first position and interconnects a second group of terminals when the switching portion is in the second position. The first and second groups of terminals differ in at least one terminal and the first group of terminals involves at least three terminals.

A low passive intermodulation (PIM) RF rotary switch comprises a plurality of center conductors connected to stationary pads, at least two rotatable pads being connected by a rotatable pad bridge. Depending on the switching state of the switch, at least two stationary pads are in close proximity to at least two rotatable pads, at a distance sufficient to generate/form a RF signal connection between the center conductors via the stationary and rotatable pads.
