|Title:||Third Intermodulation Distortion and Harmonic Generation in Mismatched Nonlinear Transmission Lines|
|Published:||January 01, 2009|
|Abstract:||This paper describes the procedure to obtain analytical expressions for the spurious signals generated in nonlinear transmission lines with impedance mismatch. Using these expressions one can rapidly extract the nonlinear parameters describing the nonlinear effects due to a nonlinear conductor, L(i) and R(i), such as in superconductors, and / or the nonlinear parameters due to a nonlinear dielectric, C(v) and G(v), such as in ferroelectrics. The resulting closed form expressions have been validated with equivalent circuit simulations. Spurious signal measurements on several coplanar waveguide superconducting and ferroelectric transmission lines have been explained using the resulting close form expressions.|
