Gbit/s-Pulse Propagation in Microstrip Discontinuities

In the last years, a variety of microstrip discontinuities have been analysed using a waveguide model with frequency dependent parameters. This contribution shows an application of these calculation techniques to fast digital signal analysis of baseband and carrier frequency circuits in microstrip. The signals are described by their Fourier coefficients, and the circuit response is calculated using the frequency dependent reflection and transmission properties of the microstrip circuit. A number of examples are given, together with experimental results, showing a close agreement between theory and experiment.
