19AS101-K03E3

Overview

The Rosenberger 19AS101-K03E3 is an SMP subminiature connectorized attenuator designed for high-frequency applications. It operates within a frequency range of 0 Hz to 26.5 GHz and maintains a characteristic impedance of 50 Ohms. The component features gold-plated beryllium copper center contacts with a minimum thickness of 1.27 µm over nickel, ensuring reliable signal transmission. The outer plug contact is constructed from brass, also gold-plated. This straight-form adapter provides precise attenuation characteristics suitable for test and measurement environments requiring stable RF performance.

Feature Summary

• Provides fixed attenuation within the SMP series for signal level control
• Utilizes gold-plated beryllium copper center contacts for durability
• Supports high-frequency operation up to 26.5 GHz
• Maintains 50 Ohm impedance for system compatibility

Applications

• Test and measurement equipment signal conditioning
• Mobile communication network infrastructure testing
• High-frequency circuit verification and calibration

Procurement Notes

Verify the specific attenuation value required for your application against the official datasheet specifications before ordering. Confirm that the SMA or SMP interface requirements match your existing hardware setup. Ensure compliance with RoHS and REACH standards as indicated in the manufacturer documentation. Check for any specific handling instructions regarding the delicate gold plating on the center contacts during installation.

Selection Notes

Select this component when a fixed attenuation value is needed within an SMP connection environment. Consider the 26.5 GHz maximum frequency limit to ensure it meets your operational bandwidth requirements. Evaluate the physical dimensions and straight orientation to confirm fit within your assembly space. Compare alternative models if variable attenuation or different connector types are necessary for your specific design constraints.

Part Context

This part belongs to the Rosenberger SMP subminiature connector family, known for flexibility in alignment tolerances.
