CATTEN-04R0-BNC

Attenuators Overview

The CATTEN-04R0-BNC is an inline RF attenuator manufactured by Crystek Corporation. It provides a fixed attenuation of 4 dB with a nominal impedance of 50 Ohms. The device operates within a frequency range from 0 Hz to 1 GHz. It supports a maximum power handling capacity of 2 Watts. The unit features BNC connectors for connection and functions reliably across an operating temperature range of -40°C to +85°C.

Attenuators Feature Summary

• Provides fixed 4 dB signal attenuation
• Features rugged BNC connector housing
• Supports 2W power dissipation
• Operates from DC to 1 GHz

Attenuators Applications

• RF test equipment
• Laboratory measurement setups
• Embedded RF systems

Attenuators Procurement Notes

Verify the specific model suffix to confirm connector type, as variations exist between SMA and BNC versions within the same attenuation series. Ensure the required power rating matches the application load, noting that higher attenuation models may have reduced power handling capabilities compared to this 4 dB variant.

Attenuators Selection Notes

Select this component when a precise 4 dB reduction is required in a 50 Ohm system. Consider the BNC interface for standard laboratory or benchtop integration. Verify that the 2W power limit exceeds the maximum expected signal power to prevent damage. Confirm the 1 GHz bandwidth covers the operational frequency spectrum.

Attenuators Part Context

This part belongs to the CATTEN series of microwave attenuators designed for rugged inline use. The series includes various attenuation values and connector types, such as SMA and BNC options. These components are engineered for stability and temperature tracking, making them suitable for precision RF applications requiring consistent performance.

Attenuators Replacement Considerations

Direct substitutes include other Crystek CATTEN-04R0 variants with different connectors, such as the CATTEN-04R0-SMA. Cross-brand replacements must match the 4 dB attenuation, 50 Ohm impedance, 2W power rating, and 1 GHz frequency range.
