This paper describes an analytical technique for Time Domain Gating of RF/microwave components. Vector fitted rational function approximations will be used to describe S-parameters in the time domain. Properties of the Laplace Transform will be taken advantage of in order to perform gating on both the time domain reflection and transmission responses. Following the development of the gating technique, theoretical and measured examples will be presented to show the applicability of the technique described. This novel approach allows for time gating of measured and synthesized data. Additionally, gated time and frequency response data can be retained and used as a design input for development of microwave assemblies.
