摘要： The present invention relates to a cavity filter and, in particular, provides an advantage of preventing performance deterioration of an antenna device by efficiently absorbing an assembly tolerance which may occur due to assembly design and preventing an interruption of an electrical flow, by comprising: an RF signal connecting part provided to be spaced apart at a predetermined distance from an external member having an electrode pad formed on one surface thereof; a terminal part which electrically connects the electrode pad of the external member to the RF signal connecting part, while absorbing an assembly tolerance existing within the predetermined distance and simultaneously preventing an interruption of an electrical flow between the electrode pad and the RF signal connecting part; a dielectric body which is inserted into a terminal insertion hole so as to surround the outside of the terminal part; and an elastic member which has a portion of the edge supported by the dielectric body and which elastically supports the terminal part by means of an operation in which a hollow part is deformed in the vertical direction when an assembly force is transmitted to the terminal part supported to pass through the hollow part, wherein the terminal part comprises one terminal brought into contact with the electrode pad and the other terminal connected to the RF signal connecting part.

摘要： Technologies for a long-lived 3D multimode microwave cavity are disclosed. In the illustrative embodiment, a series of overlapping holes are drilled into a monolithic block of aluminum forming a cavity. The dimensions of the cavity formed by the overlapping holes can be made long by drilling a long series of holes in a row and can be made high by drilling holes a certain depth into the cavity. If two dimensions of the cavity are bigger than the diameter of the holes used to create the cavity, then the cavity can support electromagnetic waves that cannot propagate through the holes, leading to a long lifetime in the cavity. A superconducting qubit or other non-linear element can be inserted into the cavity, which can controllably interact with each of several modes of the cavity. In this way, the modes of the cavity can act as components in a quantum memory.

摘要： Example embodiments of the present disclosure provide a resonator (100) and a filter (500). The resonator (100) comprises a capacitance metal sheet (110), an inductance metal sheet (120) and a mounting metal sheet (130). The capacitance metal sheet (110) is configured to generate capacitance of the resonator (100) with a top surface (202) of a metal cavity (200) for housing the resonator (100). The inductance metal sheet (120) is configured to generate inductance of the resonator (100), which is connected to the capacitance metal sheet (110) and extends to a bottom surface (204) of the metal cavity (200). The mounting metal sheet (130) is connected to the inductance metal sheet (120) and configured to mount the resonator (100) in the metal cavity (200). The example embodiments of the present disclosure can implement a resonator and a filter with high performance, small size and low cost.

摘要： Disclosed herein are radio frequency (RF) cavities and systems including such RF cavities. The RF cavities are characterized as having an insert with at least one sidewall coated with a material to prevent charge build up without affecting RF input power and that is heat and vacuum compatible. One example RF cavity includes a dielectric insert, the dielectric insert having an opening extending from one side of the dielectric insert to another to form a via, and a coating layer disposed on an inner surface of the dielectric insert, the inner surface facing the via, wherein the coating layer has a thickness and a resistivity, the thickness less than a thickness threshold, and the resistivity greater than a resistivity threshold, wherein the thickness and resistivity thresholds are based partly on operating parameters of the RF cavity.

摘要： Microwave resonance cavities and associated methods and apparatus are described. In one example, a cavity (100) comprises a first and a second input port (102, 104) for inputting microwave radiation at a first and a second frequency respectively. The microwave radiation at the first frequency may be to excite a sample in the cavity whereas the microwave radiation at the second frequency may be to interrogate a sample in the cavity for analysis. The cavity has dimensions such that it resonates at both the first and the second frequency.
