US 6,320,482 B1 · High frequency filter consisting of integral bodies

Abstract

A resonator or a filter consisting of resonators comprises an inner conductor or conductors and an outer conductor enclosing the inner conductor or conductors. It comprises a first part (201, 301, 401, 604, 701) and a second part (202, 302, 420, 501, 605, 702), of which the first part comprises at least a part of the inner conductor or conductors (203, 303, 402, 404, 703, 704, 705, 706, 707) and a part of the outer conductor (204, 205, 304, 305, 405, 406, 407, 408, 409), which is integral with the inner conductor parts and made of the same material, and of which the second part comprises such a part of the outer conductor (206, 207, 304, 305, 421, 422, 423, 424, 425) which, when connected to the first part, forms a continuous outer conductor enclosing the inner conductor.

Dependent claims

A filter comprising a plurality of resonators, each of said resonators having an inner conductor and an outer conductor, said outer conductor being shared by said plurality of resonators, said filter including a first and second piece placed against each other, said pieces being integral and homogeneous,

said first piece including each inner conductor and a part of the outer conductor,
said second piece including another part of the outer conductor, which, together with the first piece, form a continuous outer conductor for each of said resonators so that the one end of each inner conductor remains open within said continuous outer conductor,
said second piece further comprising coupling means arranged to remain within said continuous outer conductors and form at least one capacitance hat enclosing at least partly said open end of an inner conductor.
