141-3901-801

Overview

The Cinch Connectivity Solutions Johnson 141-3901-801 is a fixed SMA in-line RF attenuator module. It provides an attenuation value of 1 dB with a characteristic impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 6 GHz and handles a maximum power rating of 2 Watts. This component is designed for integration into signal paths requiring precise signal level reduction.

Feature Summary

• Provides fixed 1 dB attenuation for signal conditioning
• Maintains 50 Ohm impedance matching across the operating band
• Supports continuous power handling up to 2 Watts
• Operates effectively from DC through 6 GHz frequencies

Applications

• RF signal path attenuation
• Test and measurement equipment calibration
• Communication system signal leveling

Procurement Notes

Verify the specific SMA connector gender and orientation required for your assembly, as in-line modules often have distinct male-female configurations. Confirm that the 2W power rating aligns with your system's peak and average power levels to ensure reliable operation without thermal degradation or performance drift during extended use.

Selection Notes

Select this component when a precise 1 dB reduction is necessary within the 0-6 GHz spectrum. Ensure the host system maintains a 50 Ohm environment to minimize return loss. Consider the physical form factor of the in-line module to verify compatibility with existing chassis or cable assemblies compared to bulkhead or panel-mount alternatives.
