Ultra Wideband Monocycle pulse generation using SRD and Coupled line band pass filter with reduced ringing level

Abstract: This paper presents simple ultra wideband monocycle pulse generator by SRD and coupled line band pass filter element values for 0.5dB equal ripple. Proposed design deals with generating Gaussian pulse from square waveform as a input then using high order coupled line band pass filter we get ultra wideband monocycle pulse of 6 mv (p-p) of amplitude and pulse width of 500psec We eliminates use of lumped elements (Inductor, capacitor) and external bias circuit for generation of Gaussian pulse, due to which ringing level is reduced. Simulation is carried out using Advanced design systems (ADS).
