Problems solved by technology

The waveguide power splitter is mainly used in electronic devices in the millimeter-wave frequency band. The millimeter-wave wave velocity is narrow, the resolution is high, the available frequency bandwidth is strong, the anti-multipath effect and anti-interference ability are strong, and the guidance is accurate. Therefore, the inner wall of the waveguide cavity is required to have high roughness. , the cavity size and position accuracy are high, the structure of the waveguide power divider has certain particularity, its structure size, surface quality and position accuracy are difficult to guarantee, and the traditional processing method can not achieve satisfactory results, and cannot meet the special requirements of the design

The traditional curved waveguide is generally made by adding filling materials or heating and twisting, which will cause the cross-sectional size of the waveguide to change, and it is difficult to guarantee the dimensional accuracy of the waveguide and the surface roughness of the inner cavity.

The yield of the twisted waveguide filled with filling materials is low, the inner and outer surfaces of the waveguide are easily oxidized, it is difficult to achieve manual clamping at high temperature, and the cooling time needs to be controlled during the twisting operation, so the aperture size is difficult to control, and the deformation is relatively random. It is also difficult to clean the filling material in the body after being twisted

When the ultra-small-diameter waveguide and the flange are brazed by traditional flame brazing, due to the concentrated heating of the flame brazing, the size of the waveguide and the flange is small, and welding deformation is easy to occur. The welding deformation is large, and the waveguide diameter cannot be guaranteed.
