Abstract
A standby microwave transmitter power amplifier tube is switched into a microwave power distribution system for a phased array in microseconds when any transmitter tube feeding any one of the radiating elements falls and all the radiating elements continue to be fed by respective transmitter tubes after the switching is completed, the switching being accomplished by changing electrical length of a quarter-wavelength waveguide stub to one-half wavelength by switching a reciprocal latching ferrite phase shifter in the stub, in response to termination of microwave power from one of the feed tubes.
