Abstract
A redundant microwave system operable to process a microwave signal propagating in a microwave cavity includes a microwave cavity and two microwave processing devices. Each microwave processing device has a transmissive impedance when it is on and a reflective impedance when it is off. There is a separate coupling probe extending from each of the microwave processing devices to locations within the microwave cavity. When a primary one of the microwave processing devices is switched on and the redundant microwave processing device is switched off, its coupling probe reflects energy so that almost all of the energy flows through the primary microwave processing device. If the primary microwave processing device fails and is switched off, its coupling probe reflects energy so that almost all energy flows through the redundant device. No separate active switching device or circuit is used.
