WR-05 Waveguide Twist
The WR-05 Waveguide Twist is a precision-engineered passive component that rotates the polarization orientation of millimeter-wave signals by 90 degrees within the 140 GHz - 220 GHz frequency range, commonly associated with the G-Band.
The rectangular waveguide cross-section gradually rotates along the component length, converting between horizontal and vertical polarization with minimal signal disruption. The progressive twist profile maintains TE10 mode integrity and consistent VSWR across the full operating bandwidth. Custom twist angles (such as 45 degrees) are available on request.

Frequently Asked Questions
What is a WR-05 waveguide twist?+
A WR-05 waveguide twist is a passive component that rotates the polarization orientation of millimeter-wave signals by 90 degrees within the G-Band frequency range of 140 GHz - 220 GHz. The rectangular waveguide cross-section gradually rotates along the component length, converting between horizontal and vertical polarization.
What twist angles are available for WR-05?+
RF Essentials offers standard 90-degree twists for WR-05 waveguides. Custom twist angles such as 45 degrees can be manufactured upon request for specialized polarization requirements.
Does a waveguide twist affect signal quality?+
RF Essentials WR-05 waveguide twists use a gradual twist profile engineered to maintain excellent VSWR and minimal insertion loss across the full G-Band operating bandwidth. The progressive rotation prevents abrupt geometry changes that could degrade signal quality.
