Abstract
A multi-channel multiplexer has a substantially square shape and includes an N×N matrix with a common resonator. A plurality of input/output ports are connected to a common input/output port via respective resonators of the N×N matrix and the common resonator. The multiplexer provides a compact size, with balanced insertion losses and simple configuration to minimize phase difference of inter-resonator transitions.
