Title
A compact UWB sub-nanosecond pulse generator for microwave radar sensor with ringing miniaturization
Abstract
This paper presents a compact ultra-wideband (UWB) microwave radar transmitter. The developed design presents low-power and low-cost ultra-short pulse with a minimum of the ringing in the output waveform. Ultra-short pulse has been generated by avalanche pulse generator and sharpened with a step recovery diode (SRD). In order to improve the simulation response and to increase the rise-time of the pulses, a new model of a step recovery diode (SRD) was used as a sharpener circuit. Making the discharge path as short as possible, a minimum of the ringing has been obtained in the output pulse, around 3,6% in overshoot. Compact pulse generator circuit structure is completely fabricated using low-cost microstrip technology characteristic. The measurement results present generator Gaussian wave form pulses over 6.4 V in amplitude and 440 fall time at 100 KHz. Good Agreements between the measured and calculated result are achieved.
