New waveguide bends, twists, and straight sections feature high frequency ranges from 90 to 220 GHz in 3 waveguide bands. These include waveguide sizes of WR-8, WR-6, and WR-5 and UG-387/U mod round cover style flanges. The waveguide bends are available in 90º E-plane and 90º H-plane configurations. Waveguide twists are available in 90º, 45º right-hand, and 45º left-hand configurations. And the waveguide straight sections are available in 1, 3, 6, 9, and 12 inch lengths. All feature low VSWR performance of 1.15:1 typical.
