A Brune's Two-Port Process Applied to Lumped Element Filter Modeling
A two-port Brune's process is applied to generate a lumped element equivalent circuit model of a Chebyshev filter of order 11 based on measured data. From the measured S parameters a rational function description is obtained by a vector fitting procedure applied on tabular data. From this the Brune's lumped element equivalent circuit is directly derived. The lumped element circuit model accounts also for the circuit losses and exhibits positive circuit elements only.
