Multiplexer module design is a challenging task due to the high number of variables involved, much more with the number of filters increase. Numerical computing tools provide a suitable environment to evaluate topologies and technologies before starting the long journey to the device. For multiplexer design, the connection of filters to a common node creating a multiport network is required. A direct scattering matrix solution for an ideal star-junction multiplexer has been developed founding on the circuit theory. The resulting star-junction matrix is introduced in a matrix system with the scattering matrix of each filter to evaluate the overall multiplexer response. This approach allows the acquisition of the main parameters of the multiplexer like transmission, reflection and cross-isolation response in a compact way, achieving a good starting point for further full-wave optimization procedure.
