A new simple Ultra-Wideband (UWB) monocycle pulse generator based on step recovery diode is presented. This pulse generator uses nonlinear components with a single power supply and microstrip transmission lines. It is made up of three parts: a Gaussian pulse generator, an impulse-shaping network, and a monocycle-pulse forming circuit. The proposed circuit allows to generate ultra-short Gaussian monocycles of 270-ps pulse duration with a bandwidth of 9-GHz and a pulse repetition rate of 100-MHz.
