Brune's multiport lumped element equivalent circuits in admittance representation

摘要

A systematic algorithm for the lumped element equivalent circuit synthesis of admittance matrix of functions of complex frequency is presented. This work complements the previous work on impedance matrices by introduction of two new Brune's circuits (Type-III and Type-IV) and is also applicable to passive, reciprocal, lossy or lossless and symmetric or non-symmetric multi-port microwave circuits.
