Uniplanar picosecond pulse generator using step-recovery diode

A simple, compact, low-cost picosecond pulse generator has been developed using a coplanar waveguide and step-recovery diode. This pulse generator generates pulses of 154 ps pulsewidth and 3.5 V amplitude from an input square wave of 10 MHz repetition rate. The generated pulses have low ringing level and good symmetry. The simplicity, compactness, low cost, and good performance of the developed pulse generator make it attractive for low-cost time-domain microwave systems.
