Waveguide filter on base of dielectric the Bragg structure for millimeter waves applications

It is considered and offered the waveguide band elimination filter with the working mode H-10 that can be used in millimeter waves devices such as up, down- converters, mixer, etc. For example, if the millimeter wave up- converter operates with two input signals which have frequencies f(1), f(2) and the output signal has frequency f(3) = f(1) + f(2) (f(2) much less than f(1)), we need in small level of the signal with the frequency f(1) at the up- converter output.
