Description

technical field [0001] The invention relates to the technical field of electromechanical components, in particular to a high-precision phase-adjustable radio frequency connector. Background technique [0002] Phase-adjustable connectors can be widely used in aerospace, aviation and other fields. Generally, they are independent connector structures, and the phase adjustment is a fixed value. The phase modulation range is limited and the phase modulation accuracy is low. When the phase is continuously adjusted, the adjustment is unstable; and the phase modulation range is narrow and the phase modulation accuracy is low, which is not suitable for high-frequency signal transmission required by high-precision phase modulation, and the space adaptability is poor. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide a high-precision phase-adjustable radio frequency connector, which re...
