FREQUENCY SEPARATOR BUILT AROUND COAXIAL DIELECTRIC CAVITIES Russian patent published in 1996 - IPC

FIELD: microwave radio engineering; radio transceiving systems. SUBSTANCE: frequency separator built around coaxial dielectric cavities has case with one input and two output coaxial connectors. Mounted inside are two band filters built around coaxial dielectric cavities, coupling capacitors, and matching-coupling device in the form of two differentially connected and magnetically coupled inductance coils. Common point of inductance coils is connected to central terminal of input connector and opposing leads of coils, to coupling capacitors. Number of inductance coil turns depends on value of coupling capacitors. EFFECT: improved design. 6 dwg
