Tube shell structure of high-saturation photoelectric detector and preparation method

The invention relates to the technical field of microwave photonics, and particularly discloses a tube shell structure of a high-saturation photoelectric detector and a preparation method, and the tube shell structure comprises a packaging tube shell, and a light input structure and a radio frequency output structure which are installed at the outer side of the packaging tube shell; the packaging tube shell comprises a tube shell body provided with a cavity, a frame installed on the tube shell body, a cover plate installed on the frame and a glass sintering terminal installed on the outer side face of the tube shell body. The invention also discloses a preparation method thereof, the defects of large size, high power consumption and poor device heat dissipation of a high-saturation photoelectric detector can be effectively solved, compared with a traditional photoelectric detector tube shell, the structure can remarkably reduce the thermal resistance of the tube shell, and the application temperature of the p
