Abstract
The utility model discloses a travelling-wave tube coupler which comprises a dielectric window, a coupling waveguide, a tube shell, a window connection sleeve, a clamping rod, a spiral line, and a drift tube. The dielectric window is located at the input port of the coupling waveguide or at a joint of the coupling waveguide output port with the tube shell. The dielectric window is in seal connection with the tube shell and connected with the coupling waveguide. The interior of the tube shell is isolated from the coupling waveguide. The spiral line is fixedly connected to the shift tube. The spiral line is clamped through the clamping rod, and then the clamping rod is fixed with the tube shell which is provided with the dielectric window. According to the utility model, the travelling-wave tube coupler can be employed for avoiding air leakage caused by weld defects of a metal ceramic window and an inner conductor because of employing a metal ceramic needle-sealing window structure, and avoiding impact on a standing wave and even the reliability of a travelling-wave tube because a welding point is too large when the inner conductor and the spiral line are welded. The test voltage standing-wave ratio of a coupled structure employing the above structure is less than 1.6 in an actual use frequency band.
