Problems solved by technology
Since the waveguide / coaxial structure is used in the middle, in order to convert the TE wave into a TEM wave, it is necessary to install a short-circuit piston on the waveguide at 0.25λ, so that when the frequency is relatively low (such as P-band), the length of the connector It will be very large, which cannot meet the small size of the equipment
And the waveguide is narrow-band. In the P-band, the bandwidth generally does not exceed 20%, which cannot meet the broadband requirements.

The present invention involves a wide -frequency zone small radial rotor connector. The fixed shell of the connector is equipped with a micro -band printed board, and the micro -printed board faces the central micro -band and two places on the end surface of the rotating shell.The wire, the rotating shell of the connector is set to have a rotating -end printed board connector, and the fixed shell is set with a fixed -end printed board connector.The two ends of the printed board are connected, and the radio frequency connector of the present invention uses a micro -band line \ coaxial structure. Because the micro -band line and the coaxial axis are wide -frequency bands, the frequency band of the connector can be done very wide.By 40%, the micro -band line can be done with a printed board. The thickness can be several millimeters, or even a few millimeters of zero, so that the size of the connector product is not affected by frequency, and it can be done very small.
Description
technical field [0001] The invention relates to the technical field of connectors, in particular to a small broadband radio frequency rotary connector. Background technique [0002] At present, the through-type RF rotary connectors all adopt a waveguide-to-coaxial structure. A hollow central axis runs through the middle of the waveguide, and a waveguide-to-coaxial converter is used at the port to convert TE waves into TEM waves. Since the waveguide / coaxial structure is used in the middle, in order to convert the TE wave into a TEM wave, it is necessary to install a short-circuit piston on the waveguide at 0.25λ, so that when the frequency is relatively low (such as P-band), the length of the connector It will be very large and cannot meet the small size of the equipment. Moreover, the waveguide is narrowband. In the P-band, the bandwidth generally does not exceed 20%, which cannot meet the broadband requirements. Contents of the invention [0003] The purpose of the pres...
