Abstract

Minimum susceptance networks (MSN) can be recognized by the shape of the real and imaginary part of its input admittance. This behaviour has been harnessed in the design of contiguous band multiplexers through singly terminated filters. In this work, a new approach to MSN description introducing the input reflection coefficient phase as a key parameter is considered, which leads to understanding doubly terminated networks as MSNs under certain phase condition. A methodology to perform phase control in singly terminated filters is presented proving the existence of non-minimum susceptance singly networks. Finally, under this interpretation, a novel strategy to design star-junction multiplexers combining MSNs and non-MSNs is shown for contiguous and non-contiguous bands multiplexer.
