| Abstract |
In Accelerator technology, RF power couplers are important component to couple RF signal to travelling wave structure. Circular waveguide TM₀₁ mode is one of the symmetric modes, that is suitable to use for RF coupling. TM₀₁ mode launcher is used as an RF coupler in Accelerator technology*. Design of a compact circular waveguide TM₀₁ mode-launcher is presented in this paper. The design is based on the principle of magnetic field coupling between a wire loop and TM₀₁ mode of circular waveguide. The mode launcher exhibits high efficiency and 3.1% bandwidth at 3.2 GHz frequency with both circular and elliptical loop. Performance of the mode launcher is experimentally verified and simulated S-parameters agree with the measured results. The mode launcher is of compact size and is suitable for efficient excitation of TM₀₁ mode in circular waveguide and travelling wave structures. The launcher is also useful for cold testing of high power microwave antennas and Radars.
