Abstract

We have developed an RF power divider which is used for an RF distribution system in high-energy electron storage rings. This divider has four waveguide ports, and it can split a high RF power by a ratio of 1:2 at an operating frequency of about 508.6 MHz. Other properties are very similar to those of a magic-T. By combining this divider with a conventional magic-T, one can design an RF distribution system in which three cavities are driven by a single klystron. The design procedure of the power divider, a low-power measurement, and a high-power test result are described
