The present invention relates to an RF connector with a filter gap fixed dielectric and an RF filter.

It may include high-density connectors in the connection surface for electrical connection to be made between other members. Good isolation of the signal from ground is important, as the signal integrity and reliability requirements for operation in specific environments and applications are imperative. So, it is particularly relevant for high-frequency RF applications. In addition, these connectors and the contacts inside the connectors must be operated in a wide frequency range and in a wide variety of environmental conditions, such as mechanical, vibration, and wide temperature range.

The principle of such a filter uses resonance by a combination of inductance and capacitance. Here, the resonance means that the inductance and the capacitance are parallel to each other and have selective characteristics with respect to a specific frequency. That is, by combining an inductance component having a frequency characteristic that does not pass easily as the frequency increases and a capacitance component having a frequency characteristic that allows a better passage as the frequency increases, a desired frequency can be easily passed and an unwanted frequency can be blocked. Therefore, the filter may implement a band-stop filter or a band-pass filter suitable for the purpose by various combinations of these inductance and capacitance components.
