<p>A control signal (output 47) is achieved by measurement of the TWT (11) dynamic gain detecting (42, 43) the input and output signal to/from the TWT. A positive feedback loop couples a portion of the TWT (11) output power to the TWT input using a power combiner (19). The power output portion feedback is controlled by the control signal in order to keep the TWT operating in a desired condition to accommodate variations in gain, e.g.: saturation during TWT input pulse rise and pulse full times. The TWT is maintained in the desired condition despite changes in the condition of the TWT or in the signals applied to the TWT.</p> |
