摘要： This invention describes a high voltage, very short pulse, microwave radiating source using low-cost components, and capable of operating at high pulse repetition frequencies (prf). The source is activated by an ordinary video trigger commensurate with driving TTL logic. A trigger will cause a chain of N (where N may be 12 or greater) avalanche transistors connected in a Marx generator configuration to threshold resulting in a 1,200 volt or greater baseband pulse having a rise time of less than 100 ps and a duration of about 3 ns driving the input port of a dipole antenna. The dipole is excited by a balun. This invention achieves very short pulse duration broadband microwave radiation at pulse repetition frequencies as high as 30 kHz or greater.

摘要： A circuit (FIG. 1) for generating a current impulse comprises an avalanche transistor 2 which responds to a stimulus to apply an electrical impulse to the bases of a plurality of further avalanche transistors 3, 6. The further transistors respond to the impulse to discharge respective equal capacitors 9-12 through a laser diode 7. Further equal capacitors 22-25 connect the emitters of the transistors to the common junction of the transistor 2 and an impedance 21 to generate the electrical impulse when the transistor 2 responds to the stimulus. The arrangement of the further capacitors ensures that once one further transistor begins to conduct, the electrical stress on the others is increased, thus ensuring the further transistors simultaneously avalanche.

摘要： A pulse modulator includes a pair of avalanche breakdown transistors connected in series, a direct current source for maintaining the avalanche transistors in their quiescent states and a triggering means for applying a pulse to the avalanche transistors to switch them simultaneously from their quiescent states to their activated states to generate a high current short duration output pulse. The modulator further includes a charge storage circuit connected to the direct current source and diodes connected between the storage circuit and the avalanche transistors and poled such that the storage circuit charges during the quiescent states of the transistors and discharges the stored charge into the avalanche transistors for increasing the power output therefrom. A plurality of pairs of avalanche transistors, storage circuits, and diodes connected in a manner similar to that of the first pair may be provided in parallel therewith for further increasing the power output of the modulator.
