The utility model provides a ceramic tube shell for improving radio frequency signal transmission performance, which belongs to the technical field of photoelectric communication, and comprises a shell, a ceramic insulator and a plurality of first bonding pads, the side part of the shell is provided with an installation port, the ceramic insulator is adaptively inserted and packaged in the installation port of the shell, the outer end is arranged at the outer side of the shell, the inner end is arranged at the inner side of the shell, and the first bonding pads are arranged in the shell. The plurality of first bonding pads are evenly distributed at the upper end of the ceramic insulator in parallel, a groove is formed in the ceramic insulator and located between every two adjacent first bonding pads, the dielectric constant between every two adjacent first bonding pads can be reduced through the grooves, and then the radio frequency transmission line impedance and the radio frequency signal transmission perfo
