Description

The WR90 Rectangular Waveguide Fixed Attenuator is a passive RF and microwave component designed to reduce microwave signal power by a predetermined amount. It provides a fixed attenuation level within its specified operating frequency range, helping control signal strength in microwave transmission and testing systems. This component is suitable for radar systems, satellite communications, microwave links, antenna feed networks, RF laboratories, and microwave test and measurement equipment. It is used in applications requiring controlled signal reduction, equipment testing, and adjustment of microwave power levels. Designed for compatible WR90 rectangular waveguide assemblies, this attenuator can be integrated into microwave transmission paths where a specific reduction in signal power is required. The attenuation value is typically specified in decibels (dB), with different values available depending on the product design and application requirements. Key performance parameters include attenuation value, operating frequency range, insertion loss, VSWR, attenuation stability, and power-handling capacity. Actual performance depends on the design and manufacturer's specifications. Before ordering, confirm the required attenuation value in dB, operating frequency range, power rating, flange configuration, VSWR, and mechanical dimensions against the manufacturer's datasheet to ensure compatibility with the intended microwave system.
