Abstract : The patent describes a TWT energizing circuit for compensating for the voltage droop at a TWT cathode, comprising the use of a differential amplifier which takes a modulation pulse at one of its inputs and a feedback signal comprising a sample of the body current from the TWT helix at the other of its inputs and applies a signal representative of the difference therebetween to the TWT grid. The above-described feedback circuit forces the grid voltage to track the cathode voltage, thus maintaining a constant grid-cathode voltage drop.
