4108-10DB

Attenuators Overview

The Pomona Electronics 4108-10DB is a BNC in-line attenuator module designed for RF applications. It provides a nominal attenuation of 10 dB with a tolerance of ±0.4 dB across a frequency range of 1.1 MHz to 8 GHz. The component operates at a 50 Ohm impedance and supports a power rating of 2 Watts. It features male-to-female BNC connectors for direct series integration into signal paths.

Attenuators Feature Summary

• Provides precise 10 dB signal attenuation for RF circuitry
• Supports high-frequency operation up to 8 GHz
• Features robust BNC male-to-female inline connectivity

Attenuators Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in 50 Ohm transmission lines
• Protection of sensitive receiver inputs from high-power signals

Attenuators Procurement Notes

Verify the specific datasheet version for the 4108-10DB to confirm current manufacturing status and environmental compliance details. Ensure that the required attenuation tolerance of ±0.4 dB aligns with system specifications. Confirm connector gender compatibility for seamless integration into existing BNC infrastructure without requiring additional adapters.

Attenuators Selection Notes

Select this model when a fixed 10 dB attenuation is required within the 1.1 MHz to 8 GHz bandwidth. Consider the 2W power handling capability to ensure safe operation under expected load conditions. Verify that the BNC interface matches the surrounding equipment ports. This component is suitable for applications demanding stable performance in moderate frequency ranges.

Attenuators Part Context

The 4108-10DB belongs to the Pomona 4108 series of BNC 50 Ohm attenuators. This series includes variants with different attenuation values, such as 3 dB, 6 dB, and 14 dB models. These components are engineered for reliability in engineering research and laboratory environments, offering consistent electrical characteristics across the specified frequency spectrum.

Attenuators Replacement Considerations

Compatible substitutes include other 10 dB BNC attenuators from manufacturers like Mini-Circuits or Pasternack, provided they match the 50 Ohm impedance, 8 GHz frequency limit, and 2W power rating. Ensure physical dimensions and connector tolerances allow for direct replacement in constrained spaces.
