Description

technical field [0001] The invention relates to the fields of electronic technology and microwave diode technology, in particular to a digital high-power microwave diode reverse dynamic waveform and power loss test system. Background technique [0002] Diodes are widely used in modern high-power communication radar and other equipment, and their performance parameters (such as reverse dynamic current, reverse dynamic voltage and reverse loss power, etc.) are directly related to the stability and reliability of modern high-power communication radar and other equipment , life and efficiency. [0003] At present, the switching function of the diode in the circuit depends on the on-off characteristics of the forward and reverse currents. The instantaneous on-off of the switch is determined by the polarity of the voltage applied to both ends. There is only a small current when it is off. Since the PN junction of the diode stores many and few carriers, when the polarity of the a...
