Abstract
The utility model relates to a high performance radio frequency connecter, which comprises an external conductor, an internal conductor that is assembled inside the external conductor, as well as an insulating media that is positioned between the internal and the external conductors. The internal conductor is made by connecting a different axle typed spring plug jack and a circular rod. At the alternatively distributing section between a capacitance and an inductance of a resistance, the insulating media between the internal and external conductors is the compound insulating media that is made up of the solid and air insulating media. At the electric resistance distributing section of the resistance, the insulating media between the internal and external conductors is the solid insulating media. The solid insulating media selects the polytetrafluoroethylene or the high pressure polyethylene or the compound material that is made of polytetrafluoroethylene and the plastic as the materials. The air insulating media selects the air as the material. Compared with the similar radio frequency connecter, the reflection loss of the utility model is greatly reduced. Taking the radio frequency connecter with seventy five ohms special performance resistance as example, the reflecting loss is reduced to twenty five dB negative.

The utlity model has following beneficial effect:
1, can compare with the similar radio frequency connector that the contact pin of φ 0.8～φ 1.6 cooperates with existing, transmission performance increases substantially, and reflection loss reduces significantly, is example with the radio frequency connector in characteristic impedance 75 Europe, and reflection loss is reduced to-below the 25dB.
2, good with the coupling of cable television system equipment such as splitter, distributor, trunk amplifier, significantly reduced the debugging work load of engineering.
3, only the structure of dielectric is improved and the raw material of dielectric are easy to obtain, thereby be convenient to processing and fabricating, produce in batches.
