WR-10 Straight Waveguide
The WR-10 Straight Waveguide is a precision-engineered waveguide component that provides ultra-low loss linear signal transmission for bridging gaps in RF systems. It is specifically designed for the 75 - 110 GHz frequency range, serving as a critical building block in W-Band infrastructure.
Straight waveguide sections are drawn or electroformed to exact tolerances, providing a pure, unperturbed environment for dominant TE10 mode propagation over fixed distances. WR-10 encompasses the 75-110 GHz W-Band. It is heavily utilized for 77 GHz automotive radar systems (ADAS), requiring internal waveguide dimensions of precisely 0.100" x 0.050".

Frequently Asked Questions
Why use a straight waveguide instead of coaxial cable?+
At millimeter-wave frequencies, coaxial cables suffer from extreme dielectric loss and radiation leakage. A hollow straight waveguide removes the center conductor and dielectric, reducing insertion loss by over 80% compared to a coax cable.
Why is WR-10 the standard for automotive radar?+
The global standard for Advanced Driver Assistance Systems (ADAS) radar is 77 GHz to 81 GHz. WR-10 components (W-Band) are required for all test, measurement, and calibration systems used in the development and manufacturing of these automotive radar chips.
Can WR-10 handle high power?+
Because the aperture is only 0.100" x 0.050", the electric field density inside WR-10 is extreme even at moderate power levels. While it handles less total power than WR-28, a dry, nitrogen-purged WR-10 component can still safely pass over 100 Watts of CW power before experiencing dielectric breakdown.
