Abstract :
We have designed, fabricated, and tested a low cost tunable narrow pico-pulse generator using a 60ps transition time step-recovery diode (SRD) device. Both the pulse duration and shape are electronically controllable using PIN diodes that are optimally connected in series. A simple concept of an input-matching network was developed and implemented that can significantly minimize pulse broadening and suppress pulse distortion. The developed pulse generator circuit has a wide adjustable pulse duration covering a 300ps to 1ns range and produces either monocycle or Gaussian pulses using novel pulse shaping circuitry. The proposed structure can be easily reconfigured to include more complicated pulse shapes such as polycycle signals
