The present invention relates to a cavity filter and a connecting structure included therein. The cavity filter includes: an RF signal connecting portion spaced apart, by a predetermined distance, from an outer member having an electrode pad provided on a surface thereof; and a terminal portion configured to electrically connect the electrode pad of the outer member and the RF signal connecting portion so as to absorb assembly tolerance existing at the predetermined distance and to prevent disconnection of the electric flow between the electrode pad and the RF signal connecting portion, wherein the terminal portion includes: first side terminal contacted with the electrode pad; and the second side terminal connected to the RF signal connecting portion, wherein at least any one of the first side terminal and the second side terminal has a housing space in which the other side terminal is housed, and a part of the at least one side terminal is elastically deformed by an assembly force provided by an assembler, and applies lateral tension to the other side terminal while elastically supporting the other side terminal toward the electrode pad. Therefore, the cavity filter can efficiently absorb assembly tolerance which occurs through assembly design, and prevent disconnection of an electric flow, thereby preventing degradation in performance of an antenna device.

A connection system for a quantum computer that employs constant impedance connectors with attenuation or filtering components or both embedded therein or within an adaptor removably insertable within an adaptor housing for use in a cryogenically cooled quantum computer. The connection system provides a higher density of cables traversing through a hermetic sealed top plate, and which are accessible to chill blocks to reduce the thermal energy from the signal lines. Attenuators or filter circuits are embedded in the constant impedance connector housings, or provided in adaptors that connect on each end to form mating constant impedance connections, in order to reduce signal strength as the signal progresses through the cryogenic environment and to remove extraneous electrical signal noise.

A connector for coupling a coaxial cable to an interface port comprising a capacitor segment configured to interpose a center conductor of a coaxial cable and an RF interface and an outer conductor segment extending over and electrically shielding the capacitor segment. The capacitor segment comprises an inner and outer pin having a dielectric insulator therebetween and is configured to electrically connect an inner conductor of the coaxial cable to the RF interface port. The capacitor segment facilitates the passage of RF energy from the inner conductor of the coaxial cable to the RF interface while inhibiting the passage of electric current through the capacitor segment to the RF interface.
