RF Network Analysis


The network analysis determines the circuit's behavior as seen through its port(s). It generates data in the form of Z (impedances), Y (admittances), S (scattering), and H (the inverse of S). In the case of a two-port analysis with Z results, the four results are Z11 (the input impedance), Z22 (the output impedance), and Z12 and Z21 (the cross-impedances). Network analysis is often used for analysis of circuits that operate at very high frequencies, and components operating at these frequencies are often modeled with tables of S-parameters.
