WR-112 to N Female Right Angle Waveguide to Coax Adapter, UDR-84, 6.57-9.99 GHz

WR-112 to N Female Adapter for Professional C-Band Applications

This WR-112 waveguide to N female coaxial adapter is designed to provide a precise, stable and low-loss transition across the 6.57–9.99 GHz operating range. With its right-angle geometry, it is an ideal solution for compact RF and microwave assemblies where space optimization, mechanical reliability and repeatable electrical performance are essential.

Manufactured by QAXIAL, this adapter is engineered for professional C-Band waveguide systems and high-performance RF applications. The N female interface, compliant with MIL-STD-348A, ensures reliable coaxial connectivity, while the WR-112 / IEC R84 waveguide interface provides compatibility with standard rectangular waveguide networks.

WR-112 / UDR-84 Waveguide Interface

The adapter features a rectangular cover flange compliant with EIA UG-1735/U and IEC UDR-84 standards. This flange configuration ensures accurate mechanical alignment, stable mating and reliable integration into professional waveguide systems.

Its right-angle construction allows the coaxial connector to be positioned perpendicularly to the waveguide axis, simplifying installation in systems with limited space or specific routing requirements. Precision machining and controlled internal geometry help maintain impedance continuity and minimize RF discontinuities across the operating band.

Professional Electrical Performance

This WR-112 to N female adapter is designed for 50 Ω impedance systems and offers excellent RF performance, with a specified VSWR ≤1.20 and insertion loss ≤0.20 dB. These characteristics make it suitable for applications requiring low reflection, efficient signal transfer and consistent repeatability.

The adapter is built with a rugged aluminium waveguide body with gray paint finish, a passivated stainless steel N connector body and a gold-plated BeCu center pin. These material choices support long-term reliability, stable contact performance and resistance to demanding operating conditions.
