R422120020

Overview

The R422120020 is a fixed coaxial attenuator manufactured by Radiall USA, Inc. It features a TNC connector interface and provides an attenuation value of 20 dB. The device operates within a frequency range of 0 Hz to 6 GHz with a characteristic impedance of 50 Ohms. It supports a maximum power handling capacity of 50 Watts. The unit is designed as an in-line module for RF applications.

Feature Summary

• Provides precise 20 dB signal attenuation for RF systems
• Utilizes robust TNC connector interface for secure mating
• Engineered for high power handling up to 50 Watts
• Operates effectively across a wide bandwidth from DC to 6 GHz

Applications

• RF signal level control in communication systems
• Test and measurement equipment calibration
• Protecting sensitive components from high power signals
• Impedance matching in microwave circuits

Procurement Notes

Verify the specific datasheet version for the R422120020 to confirm mechanical dimensions and material specifications. Ensure that the operating environment does not exceed the stated 50W power limit or 6 GHz frequency range. Cross-reference the TNC connector gender and coupling type with system requirements to guarantee compatibility. Confirm that the manufacturer's environmental ratings meet application standards.

Selection Notes

Select this component when a fixed 20 dB attenuation is required at frequencies up to 6 GHz. The TNC interface is suitable for applications requiring reliable connections without frequent disconnection. Consider the 50W power rating for high-power transmission lines. Ensure the 50 Ohm impedance matches the rest of the RF chain to minimize reflections.

Part Context

This part belongs to Radiall's line of fixed coaxial attenuators. These components are designed to reduce signal amplitude without introducing significant distortion. The TNC variant offers a balance between performance and ease of use. The series supports various attenuation values and connector types for diverse RF needs.

Replacement Considerations

Direct substitutes must match the 20 dB attenuation, 50 Ohm impedance, and TNC interface. Verify that alternative parts support the same 6 GHz frequency range and 50W power handling. Check for identical mechanical dimensions to ensure fitment in existing assemblies.
