RESONATOR ASSEMBLY AND FILTER

摘要

A resonator assembly comprising a resonant member within a conductive resonator cavity is disclosed. The resonant member extends from a first inner surface of the resonator cavity towards an opposing second inner surface. A main portion of the resonant member has a substantially constant first cross sectional area. A cap portion of the resonant member extending from the main portion towards the opposing second inner surface has a progressively increasing cross sectional area increasing from the first cross sectional area adjacent to the main portion to a larger cap cross sectional area at an end of the resonant member, the larger cap cross sectional area being at least 1.i times as large as the first cross sectional area. The resonant member may also have a flared section at the other end giving the resonant member an hour glass type shape.

1. A resonator assembly comprising a resonant member within a conductive resonator cavity;
said resonant member extending from a first inner surface of said resonator cavity towards an opposing second inner surface; a main portion of said resonant member having a substantially constant first cross sectional area; a cap portion of said resonant member extending from said main portion towards said opposing second inner surface and having a progressively increasing cross sectional area increasing from said first cross sectional area adjacent to said main portion to a larger cap cross sectional area at an end of said resonant member, said larger cap cross sectional area being at least 1.1 times as large as said first cross sectional area; wherein said resonant member has a length of between an eighth to a sixteenth of a resonant wavelength of said resonator assembly.
