<title>A pulser with inverted microstrip line for time-domain reflectometry</title>

Abstract

The paper presents a pulse generator dedicated for time domain relectometry system. The idea of the pulser delivering step pulses with picosecond transition time together with its experimental realization are described. Main features of the presented pulser are: the circuit for shaping output pulses consisting of several stages (each of them containing Step Recovery Diode) connected by inverted microstrip line and the controlled delay of the (also generated) oscilloscope trigger pulses. Time-domain measurement illustrate the achieved results.
