R422120030

Attenuators Overview

The R422120030 is an in-line RF attenuator manufactured by Radiall USA, Inc. It features a TNC connector interface and provides a fixed attenuation value of 20 dB across a frequency range of 0 Hz to 6 GHz. The component is designed for 50 Ohm impedance systems and supports a maximum power handling capacity of 100 Watts. It utilizes silicon technology and is packaged in bulk quantities.

Attenuators Feature Summary

• Fixed 20 dB attenuation performance
• TNC connector interface for secure mating
• High power handling capability up to 100W
• Broadband operation from DC to 6 GHz

Attenuators Applications

• RF signal level reduction in test and measurement equipment
• Attenuation stages in wireless communication systems
• Protection of sensitive receiver inputs in radar applications
• Signal conditioning in microwave instrumentation

Attenuators Procurement Notes

Verify the specific datasheet version for the R422120030 to confirm mechanical dimensions and material specifications prior to integration. Ensure that the operating environment remains within the specified temperature range and power limits to maintain performance integrity. Cross-reference the TNC connector gender and mating requirements with the system design to ensure compatibility.

Attenuators Selection Notes

Select this component when a fixed 20 dB attenuation is required at frequencies up to 6 GHz. The 100W power rating makes it suitable for high-power applications where standard attenuators may fail. The TNC interface offers robust mechanical stability compared to smaller connectors, making it ideal for industrial or outdoor environments requiring reliable connections.

Attenuators Part Context

This part belongs to Radiall's line of coaxial attenuators, which are designed for precision RF applications. The series includes various attenuation values and connector types to support diverse system architectures. These components are engineered to provide stable performance with low VSWR, ensuring minimal signal reflection in critical RF paths.

Attenuators Replacement Considerations

Direct substitutes include other Radiall TNC attenuators with identical 20 dB attenuation and 100W power ratings, such as the R422120040 if higher power (150W) is acceptable. Verify that any replacement maintains the same 50 Ohm impedance and frequency range to ensure system compatibility.
