Abstract :
The output power of two Cherenkov devices is combined using a circular waveguide T-junction. The microwave sources are driven by the same high voltage pulser to prevent phase difference in the outputs. This passive power combiner not only combines the power, but also outputs a Gaussian beam when a TM01-mode is used as the input. An efficient serpentine mode converter has been used as the basis of the power combiner design. A conversion efficiency of 85% with a Gaussian pattern is achieved in simulations and is described in this paper.
