An SRD narrow pulse signal generator basing on the clock drive belongs to the electronic technical field, which relates to the technique of super wide-band communication, pulse radar and pulse source. The generator comprises a clock source, a coupling capacitance, a resonance matching circuit, a pulse forming circuit and a pulse shaping circuit. The generator has simple circuit and convenient modulation. Complexity and power consumption of the circuit are reduced with the help of an automatic bias circuit of SRD which is formed by the matching network and the load resistance, extended power consumption and thermal noise of the circuit are further reduced since all the resonance matching circuits adopt reactive element, particularly a lumped inductance L3 and a Schottky diode are introduced to be a shaping circuit, pulse stretching is effectively inhibited, and pulse delay fall time is greatly compressed, and simultaneously the problem of pulse side lobe and overshoot can be effectively solved. Narrow pulse signals which are generated by the generator have good wave shaping symmetrical characteristic, which can be used as triggering source of Gaussian pulse of higher order differential with high quality and the signal source of super broadband wireless communication and the impacting radar.
