Propagation of picosecond pulses on microwave striplines
Abstract
Microstrip lines have been widely used as basic components of microwave integrated circuits. When the wavelength becomes comparable to the cross-sectional dimensions, dispersion becomes significant. Relatively little attention has been paid to dispersion in microstrip lines fabricated on semiconductors. These structures have recently been used in the field of picosecond optical pulse detection and picosecond electrical pulse generation. In the case of these short pulses, pulse distortions due to dispersion may be considerable. A numerical analysis is conducted of dispersion in a microstrip line. The calculated output pulse shapes show the distortion of the pulses in the time domain. The results provide an indication of what might occur in connection with picosecond electrical pulse generation. Attention is given to numerical calculations, an analytical approximation, and an analysis of pulses generated from photoconductive switches.
