MICROWAVE DIPLEXER Russian patent published in 2025 - IPC H01P1/203 

FIELD: microwave equipment.

SUBSTANCE: microwave diplexer contains a dielectric substrate, on one side of which a grounded base is applied, and on the second – strip conductors of the matching circuit, which is made in the form of a pin, which strip conductor one end is open, and the common input (port) is connected to the second one, and the low-frequency and high-frequency channels two band-pass filters resonators, each of which is formed by three resonators, wherein all high-frequency channel resonators and two low-frequency channel bandpass filter resonators are made in form of a pin. In the bandpass filter of the low-frequency channel, the input resonator has a rectangular shape and is grounded on one side, and is also placed such that one of its edges faces the inner edge of the matching circuit conductor near its grounded end.

EFFECT: reduced dimensions of the diplexer.
