Characterization of picosecond pulse propagation in a microstrip line divider

Many extremely broad bandwidth circuit components have to be newly developed for practical applications of ultrashort electrical pulses. Theoretical and experimental investigations of the transmission properties of picosecond pulses through a microstrip line divider are reported. Full-wave analysis results in the frequency domain are incorporated into a Fourier transform algorithm for computer simulations of pulse propagation through a 3-dB microstrip line divider with a curved-line branching circuit pattern. Excellent agreement has been found between the theoretical predictions and the results of experimental measurements.>
