4108-14DB

Attenuators Overview

The Pomona Electronics 4108-14DB is a connectorized attenuator featuring BNC interfaces with a nominal impedance of 50 Ohms. It provides a maximum attenuation of 14 dB with a tolerance of 0.9 dB. The device supports frequencies up to 8 GHz and has a power rating of 2 W at 70°C. Operating temperatures range from -55°C to +102°C. Constructed from brass and beryllium copper with Teflon insulation, it serves as a precision RF component for signal level adjustment in test and measurement applications.

Attenuators Feature Summary

• Provides fixed 14 dB attenuation using BNC connectors for reliable interconnection
• Operates within a wide frequency range extending up to 8 GHz
• Features robust construction utilizing brass and beryllium copper materials

Attenuators Applications

• RF signal level reduction in laboratory test setups
• Impedance matching in 50 Ohm transmission lines
• Protection of sensitive measurement instruments from high power signals

Attenuators Procurement Notes

Verify the specific attenuation value matches the required circuit design, as this model provides 14 dB. Confirm that the BNC interface type aligns with existing equipment ports. Ensure the 2 W power rating is sufficient for the intended operating conditions. Check that the frequency response up to 8 GHz meets system requirements. Validate material specifications against environmental constraints.

Attenuators Selection Notes

Select this model when a fixed 14 dB attenuation is required in a 50 Ohm system. Consider the BNC connector compatibility with current hardware infrastructure. Evaluate the 8 GHz frequency limit against operational bandwidth needs. Assess the thermal performance capabilities relative to ambient temperature variations. Compare physical dimensions and weight against space constraints in the assembly.

Attenuators Part Context

This component belongs to the Pomona 4108 series of connectorized attenuators. The series includes variants with different attenuation values such as 3 dB, 6 dB, and 10 dB. These devices are designed for general-purpose RF testing and measurement environments. The manufacturer emphasizes reliability and precision in their test accessory lineup.

Attenuators Replacement Considerations

Compatible substitutes include the 4108-3DB, 4108-6DB, and 4108-10DB models from the same series. These alternatives offer different attenuation levels while maintaining identical BNC interfaces and 50 Ohm impedance. Verify that the specific dB value required by the application matches the substitute part number.
