BROADBAND FERRITE DECOUPLER BASED ON LUMPED ELEMENTS Russian patent published in 2016 - IPC H01P1/32 

FIELD: radio engineering, communication.

SUBSTANCE: broadband ferrite decoupler based on lumped elements comprises, arranged between two ferrite elements placed coaxially above each other, a Y-link in the form of a system of intertwined flat conductors and a band-expanding circuit between the common point of flat conductors and the housing in the form of a series circuit with inductance, consisting of two inductors of different values, connected in parallel to each other. The inductance of the band-expanding circuit is realised in the form of straight inductive conductors of the same length and different width, placed on the axis of symmetry of a circulator.

EFFECT: simple and improved technological effectiveness of the design of the broadband ferrite decoupler, reduced insertion losses.
