732870031

Attenuators Overview

The Molex 73287-0031 is a straight male RF attenuator designed for high-frequency signal management. It features an SMA interface with plug-to-jack connectivity and maintains a standard 50-ohm impedance. The component provides a fixed attenuation of 3 dB across a frequency range extending up to 18 GHz, with some sources citing a maximum operational limit of 23 GHz. It is rated for 2 watts of power handling capacity and utilizes an in-line module construction.

Attenuators Feature Summary

• Provides controlled signal reduction via fixed 3 dB attenuation
• Maintains stable 50-ohm impedance for system matching
• Supports high-frequency operation up to 18 or 23 GHz
• Handles continuous power loads of 2 watts

Attenuators Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• High-frequency circuit protection and signal conditioning

Attenuators Procurement Notes

Verify the specific datasheet version to confirm if the upper frequency limit is 18 GHz or 23 GHz, as documentation varies. Ensure the SMA connector gender matches the application requirements. Confirm power rating compatibility with the system's thermal constraints before integration.

Attenuators Selection Notes

Select this component when a precise 3 dB reduction is required for SMA-based RF paths. Consider the 2W power rating against peak signal levels. Evaluate the physical size constraints for in-line installation within the assembly.

Attenuators Part Context

This part belongs to the Molex RF Attenuator product line, specifically the connectorized attenuator category. It serves as a passive component for managing signal strength in coaxial environments without introducing significant reflection or distortion.

Attenuators Replacement Considerations

Compatible substitutes include other 3 dB SMA male-to-female attenuators from Molex or third-party manufacturers offering identical 50-ohm impedance and comparable frequency ranges up to 18/23 GHz.
