  • Automatic phase compensation circuit for paralleling power amplifiers in the microwave frequency range
    Patent number: 4041413
    Abstract: A system for phase control of multiple high power microwave frequency amplifiers. A pilot frequency lower than the frequency to be amplified is used to modulate the microwave signal. The pilot frequency is detected at the output of the amplifier stage and phase compared with the original pilot frequency. Any difference is used to produce a phase correction signal applied to the amplifier. Phase modulatable traveling wave tubes are the power amplifiers. One alternate embodiment involves a steerable array employing an additional pilot frequency correction introduced into the pilot signal. In another embodiment a cross field amplifier is placed in series with a traveling wave tube amplifier in the phase correction loop.
