Development of four kinds of waveguide power divider for S band
  Four kinds of waveguide power dividers with different structures working at 2.856 GHz are developed. By comparing the simulation performances of these four structures, the power divider with matching rod in the middle of its structure has got the best performance and finally be chosen for fabrication. The prototype has got qualified microwave measurement results as well as the high vacuum performance. It also works stable during the whole progress of microwave commissioning.
