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.

An isolator includes a conditioning circuit configured to filter signals communicated therethrough. The isolator also includes a coupling member comprising an anti-rotation feature. The anti-rotation feature is configured to prevent the conditioning circuit from rotating with respect to the coupling member to maintain a stable ground contact for the conditioning circuit.

The first and second annular circuits are configured to provide radio-frequency (RF) coupling with the coupling member.

Common mode noise can exist on an outer conductor of a female F-type port of a RF-device, like a cable modem box or cable TV set-top box. The present invention utilizes a jumper wire attached to an electrically conductive connector, having a shape and size to fit around a base of the F-type female coaxial port. The jumper wire carries the common mode noise away from the outer conductor of the port. In a first embodiment, the jumper wire is connected to a ground line of a household outlet. In a second embodiment, the jumper wire dissipates the noise signal by interacting with one or more ferrites. In a third embodiment, the jumper wire carries the noise signal to a shielding layer of a coaxial cable, which may further carry the noise signal to one or more ferrites or a ground connection.

A coaxial power sensor assembly configured to provide a broadband matched termination utilizing coplanar waveguide topology while simultaneously providing a source of heat energy for a surface mount chip thermistor element to measure applied input power. The coaxial thermal power sensor is comprised of a thin film resistive device on a dielectric substrate and a surface mount chip thermistor element placed in close planar proximity to the resistive device in order to maximize the heat flux via a closely coupled thermal path to the thermistor and alter the bias current through the resistance to be measured. The power sensor is intended to function from DC to 70 GHz, but the same should not be construed as a limitation.
