The spice, circuit analysis program has been widely accepted as an industry standard for electronic circuit analysis, and it is used at colleges and universities. This paper describes the analysis of two model of directional coupler that can be used to obtain node voltages proportional to incident, refected and transmittied signals.
These models are based on a previously developed multiple coupled node transmision line spice model. From computed node voltages, S-parameter are computed using the pspice post processor, probe, as an example for a filter consisting of transmission line sections. The result of this example are good and microwave analysis can be conducted with pspice, which can be a costeffective and readily useful analysis tool for educators and practicing engineers.
