Abstract

An Nx-plexer for impedance matching a set of N filters with distinct passbands to an antenna. The Nx-plexer includes a set of reactive elements or networks coupled in series between a proximal node and a distal node, wherein one or more intermediate nodes between the proximal and distal nodes separate one or more distinct pairs of the reactive elements or networks, respectively; a set of filters coupled to the proximal node, the one or more intermediate nodes, and the distal node, respectively, wherein center frequencies of passbands of the filters coupled to the proximal node, the one or more intermediate nodes, and the distal node, are staggered in a particular frequency direction, respectively, wherein the distal node is coupled to an antenna. Different variations of the aforementioned Nx-plexer are also described.
