WR75 Coupled Waveguide Attenuator for High Power Broadband Signal Control

This product is a professional Waveguide Attenuator featuring a coupled design for high power broadband applications. The attenuator operates across the 9.84GHz to 15GHz frequency band in the WR75 waveguide size and is constructed from copper with silver plating and paint coating for excellent conductivity and corrosion resistance. As a Coupled Attenuator, it provides flat frequency response across its operating band, ensuring uniform attenuation at all frequencies within the range. The component features a FBP120 flange interface for compatibility with standard WR75 waveguide systems. This attenuator is essential for signal power balancing, measurement system calibration, signal simulation, and interference suppression in microwave systems where higher power handling is required.

This Coupled Attenuator delivers excellent electrical performance across its operating frequency range. The Voltage Standing Wave Ratio is rated at 1.25 or lower, ensuring good impedance matching with minimal signal reflection. The attenuation value is 40dB with a tolerance of plus or minus 2dB, providing precise signal reduction for measurement and calibration applications. The average power handling is suitable for higher power signal processing compared to standard waveguide attenuators, making this component ideal for demanding applications where power levels exceed the capability of conventional attenuators. The silver plated copper construction provides superior conductivity and protects against oxidation, ensuring reliable performance across the full frequency band. The flat frequency response characteristic ensures that signal quality is maintained consistently across all operating frequencies.

One clear strength of this Coupled Attenuator is its ability to handle higher power levels while maintaining flat frequency response and precise attenuation. It is widely used for signal power balancing, measurement system calibration, signal simulation, clutter and interference suppression, and device protection. Common applications include communication systems, radar systems, and microwave measurement fields where broadband signal control is required. The coupled design allows this attenuator to serve as an attenuation standard for high precision measurements. The standard FBP120 flange interface ensures compatibility with common WR75 waveguide components. The robust construction provides long term reliability even under demanding conditions, making this attenuator suitable for both laboratory and field applications.

In practical use, this Coupled Attenuator handles professional microwave measurement and signal control tasks very well. For test laboratories, it provides reliable broadband signal control for high precision measurements. For radar systems, it enables power level adjustment and signal conditioning in transmit and receive paths. For communication systems, it ensures proper signal levels for system optimization. The silver plated copper construction provides good durability and conductivity at X and Ku band frequencies. The flat frequency response ensures uniform attenuation across the entire operating band. Custom options are available for attenuation value, frequency band, and finish upon request. This Coupled Attenuator stands as a solid example of a well designed high power broadband attenuation solution for demanding microwave applications.
