ABSTRACT:
A method for configuring a microwave multiplexing network having a first channel filter and a second channel filter and an interconnect in order to improve channel performance. The top ends of the first and second channel filters are coupled to the closer of the top and bottom surfaces of the interconnect according to interconnect spacing values and filter to interconnect values. Interconnect values and filter to interconnect values are determined by selecting interconnect spacing values and filter to interconnect values to ensure that a pole is formed causing an additional real reflection zero to be brought into the passband of the microwave multiplexing network thereby increasing the filter order by one. Then interconnect spacing values and filter to interconnect values as well as the internal filter dimensions are selected to ensure that the return loss of the microwave multiplexing network is less than a predetermined return loss level.
