Circular Waveguide To Coaxial Adapter for Ka Band Signal Interface

Circular waveguide systems offer advantages in polarization handling and rotary applications, but connecting them to standard coaxial test equipment creates a problem. Engineers struggle with impedance mismatches, lack of compatible connectors, and the need for bulky adapter assemblies. The signal quality degrades at the transition point, and measurement accuracy suffers.

The Circular Waveguide Coaxial Adapter solves this issue. As a Waveguide To Coaxial Adapter, it provides seamless transition between circular waveguide and 2.92-K coaxial interface. It covers the 27.5GHz to 31GHz Ka band with low VSWR and low insertion loss. The copper body with silver plating ensures good conductivity and corrosion resistance. The adapter works as both an interface bridge and a performance assurance device.

This adapter features an 8.3mm circular waveguide port and a 2.92-K female connector. The 0.5dB insertion loss and 1.3 VSWR deliver clean signal transmission. The compact design fits tight spaces. Power handling suits typical test and measurement applications. Works with standard circular waveguide components and coaxial test cables.

Ideal for Satellite Communication ground stations, Ka band radar systems, test and measurement laboratories, R&D teams developing circular waveguide components, and defense applications requiring circular to coaxial interface.
