摘要：
A new ultra wideband (UWB) tunable monocycle pulse generator has been developed. The monocycle pulse was generated through differentiation of an UWB Gaussian or rectangular pulse, which was obtained by differentiating a step pulse generated by step-recovery diode. The tunable differentiation of step pulse was obtained based on a tunable delay line structure using electronic controlled switches. The tunable differentiation of Gaussian or rectangular pulse was done using a monocycle pulse shaping circuit with an RC network based on varactor diode. Measurement result shows good-shape monocycle pulse with pulse width of 400-850 ps and low ringing level.
