Abstract: An automatic protection system for receiver circuitry includes a waveguide switch having a permanent magnet attached to a rotatable manifold and at least one electromagnet axially surrounding the rotatable manifold. An automatic actuation circuit is coupled to the waveguide switch. The automatic actuation circuit includes an RF power detector for detecting incident RF power around the rotatable manifold and generating a detection signal therefrom, a controller coupled to receive the detection signal and for generating at least a first control signal based on the detection signal, and a magnet current driver coupled to receive the first control signal and coupled to the electromagnet. The magnet current driver provides a first drive signal responsive to the first control signal that automatically rotates the rotatable manifold into a protected position that implements a protected path, such as when the incident RF power exceeds a predetermined RF power level.

Abstract: An apparatus directs two high-power UHF transmitter signals to one or the other or a combination of output destinations as determined by the setting of control components. Redirection between outputs can be performed continuously under full power. Using the apparatus, synchronous amplifiers directed to the same output produce a signal with all of the power of both amplifiers. The signals can be shifted to the station load without shutting down the amplifiers. After a failure, the remaining amplifier can be redirected to provide a clean signal.

Abstract: These and other objects of the present invention are provided by an ambient load waveguide switch mounted between a feed horn and a low noise amplifier in a ground based antenna. The ambient load waveguide switch includes a housing assembly having a through path. A shuttle assembly is positioned within the housing assembly and moves linearly within the housing assembly on a guide assembly between a first position and a second position. In the first position, the shuttle assembly has a waveguide alignable with the through path of the housing assembly. In a second position, the shuttle assembly has an ambient load element alignable with the through path of the housing assembly. A motor assembly moves the shuttle assembly in a first direction and compresses a first spring to bias the shuttle assembly into the first position. The motor assembly moves the shuttle assembly in a second direction and compresses a second spring to bias the shuttle assembly into the second position. There are horizontal and vertical alignment mechanisms for accurately and repeatedly positioning the waveguide and the ambient load cell in the first and second position, respectively. Advantageously, the guide assembly is relatively flexible resulting in long life and infrequent calibration. The waveguide provides a straight line path and is under two inches in length.

Abstract: Microwave switches are shown which can route signals in an operating frequency band along selectable signal paths between a plurality of microwave ports. The switches are especially suited for forming switching systems that can substitute redundant components for failed components. In one embodiment, waveguide transmission lines and microwave ports are serially coupled in a closed loop with other waveguide transmission lines arranged transversely across the loop. In another embodiment, waveguide modules are formed of three waveguides coupled to a microwave port and the waveguide modules are serially arranged. In each waveguide of these embodiments, conductive reeds are movable between a signal-attenuating position abutting the interior surface of the waveguide and a signal-conducting position substantially coaxial with the waveguide and coupled to the microwave ports at each waveguide end.
