Abstract:

A novel approach for solving complicated nonreciprocal transmission line(NTL) problems using standard Smith Chart was proposed. Based on a nonlinear mapping, it transforms the parameters of NTL model into the parameters of traditional reciprocal transmission line(RTL) model and, as a result, the design and calculation in NTL can be easily done by using a standard Smith chart(SSC). The feasibility and convenience of the approach was tested through the complete design process of NTL single-stub series-matching and NTL double-stub parallel matching network.

Key words: nonreciprocal transmission line, generalized Smith chart, standard Smith chart
