Mi-Wave’s 690 Series flanged waveguide sections are available in standard waveguide sizes from 8 to 500 GHz. Each section is precisely fabricated using MIL-SPEC waveguide and flanges. Precise control of the fabrication processes eliminates waveguide discontinuities and distortion. The 690 Series waveguide is available in a wide variety of materials. Available lengths are limited by raw waveguide which varies in length with each waveguide size. Check with Mi-Wave’s sales engineer for available lengths. Longer sections different wave-guide materials, and special flanges are all available upon request.
