05K1P5-S2BS3

Overview

The Rosenberger 05K1P5-S2BS3 is an in-line RF attenuator module designed for N-Type coaxial interfaces. It provides a fixed attenuation of 5.72 dB with a nominal impedance of 75 Ohms. The component operates within a frequency range of 0 Hz to 18 GHz and supports a maximum power handling capacity of 1 Watt. Constructed as a precision test and measurement accessory, it ensures stable signal reduction across its specified bandwidth while maintaining the structural integrity required for high-frequency applications.

Feature Summary

• Provides precise fixed signal attenuation for RF circuit analysis
• Engineered for stable performance in 75 Ohm transmission systems
• Supports broadband operation up to 18 GHz frequency limit

Applications

• Vector Network Analyzer (VNA) calibration setups
• RF signal chain level adjustment in test environments
• Attenuation insertion for 75 Ohm video or data transmission lines

Procurement Notes

Verify the specific impedance requirement of 75 Ohms against your system design, as this model differs from standard 50 Ohm variants. Confirm that the 1 Watt power rating aligns with your operational signal levels to prevent damage. Ensure compatibility with N-Type connectors on both input and output sides. Check for any specific calibration certificates if used in high-precision metrology applications.

Selection Notes

Select this component when a fixed 5.72 dB reduction is required in a 75 Ohm environment. It is suitable for applications where variable attenuation is unnecessary and space constraints favor an inline module over discrete components. Consider the 18 GHz upper frequency limit to ensure it meets the highest harmonic or fundamental frequency requirements of your signal source.

Part Context

This part belongs to Rosenberger's portfolio of precision RF accessories and attenuators. It complements their broader range of calibration kits and interconnect solutions. As a dedicated attenuator, it serves specialized roles in test equipment and measurement infrastructure, distinct from their general-purpose connector assemblies.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must verify exact electrical parameters, specifically the 5.72 dB value and 75 Ohm impedance, when sourcing alternatives from other manufacturers.
