Synthesis of n-Port Networks on Two-Tree Port-Structures

This paper presents some of the salient features of an
n + 2
terminal, n-port, network synthesis procedure which is capable of producing various equivalent realizations having different element branch topologies on appropriate port-tree structures. The method is based on
n + 1
terminal synthesis techniques and on the concept of paralleling three networks. One network provides the necessary intersubtree transmission properties but contains both positive and negative elements, the second network provides no intersubtree transmission but introduces parasitics among the ports of a given subtree, and the third network completes the requirements of the subtree. The method is basic, simple to apply, and is in the state of development which urges its generalization.
