Precision Waveguide offers a series of transitions used to connect waveguide of different sizes that have overlapping frequency ranges. The typical VSWR is less that 1.10 over the full frequency range. Shorter transitions are available where length requirements are more critical than a low VSWR. Please contact the factory for your custom requirement. Units are furnished with standard cover to cover flanges and have an iridite finish.
