  • Wave guide pulse generator producing narrow width pulse
    Patent number: 3955157
    Abstract: A high energy pulse having a very narrow pulse width is generated utilizing a wave guide pulse generator. A first pulse having a pulse width greater than the desired pulse is modified to have a well-defined leading edge and is then coupled to a first quadrature hybrid. A second pulse, shifted in phase relative to the modified first pulse, is generated in the first hybrid from, and in addition to, the modified first pulse. The phase-shifted second pulse travels the length of a conventional wave guide so that the pulse is delayed before entering a second quadrature hybrid. The second quadrature hybrid receives the modified first and phase-shifted second pulses andd phase shifts the second pulse so that the phase thereof is opposed to the phase of the modified first pulse. The modified first pulse is then combined with the opposed phase-shifted second pulse.
