Black Oxidized Aluminum Waveguide Coax Interface

WR51 End Launch Waveguide To Coaxial Adapter for K Band System Integration

Connecting coaxial cables to waveguide runs at K band is often harder than it should be. Standard adapters either take up too much space or fail to deliver stable performance across the full 14.5GHz to 22GHz band. Signal reflections, insertion loss, and unreliable measurements are common headaches during system integration and testing.

The WR51 End Launch Waveguide Coaxial Adapter solves this directly. This Waveguide To Coaxial Adapter connects at the end of the waveguide run without requiring extra bends or sections. It covers the full K band with low VSWR and low insertion loss, making it a reliable interface between waveguide and coaxial transmission lines. The end launch design saves space and simplifies system layout.

This adapter features an FBP180 flange on the waveguide side and an SMA-K connector on the coaxial side. The aluminum body with black oxidation finish is lightweight and corrosion resistant. It handles typical test and measurement power levels and works with standard WR51 components. Ideal for test labs, radar system integration, satellite ground stations, R&D setups, and defense applications.

FAQs

Q1: Can this adapter be customized for other waveguide sizes or connector types?
A1: Yes. We support customization from WR975 to WR10 and various connector types including 2.92-K, N-K, and SMA-J.

Q2: What is the difference between end launch and orthogonal adapters?
A2: End launch connects at the waveguide end; orthogonal has a 90-degree interface for tight spaces.

Q3: Is this suitable for outdoor use?
A3: Yes. The black oxidized aluminum body resists corrosion and the FBP180 flange provides a secure connection.
