Abstract:
An integrated circuit multiplexer comprising:a waveguide having an interior cavity, first RF input port, and a first and second output ports; wherein said waveguide defines a right rectangular prism which has a rectangular cross-sectional area having a width L1 and a depth L2, where L12a dielectric structure positioned in said cavity; an RF input feed attached to said dielectric structure that extends through said RF input port; a first RF output feed attached to said dielectric structure that extends through said first RF output port; a second RF output feed attached to said dielectric surface that extends through said second RF output port; a first resonator pair mounted to said dielectric structure between said RF input feed and said first RF output feed, and electrically connected to said waveguide; and a second resonator pair mounted to said dielectric structure between said RF input feed and said second RF output feed, and electrically connected to said waveguide such that said first and second resonator pairs are generally coplanar.
