732870040

Attenuators Overview

The Molex 73287-0040 is a fixed RF attenuator designed for high-frequency applications. It features an SMA male-to-female in-line configuration, providing a precise attenuation value of 4 dB. The component operates within a frequency range extending from 0 Hz to 18 GHz. It is rated for a maximum power handling capacity of 2 watts and maintains a characteristic impedance of 50 ohms. The unit is constructed as a straight module without hexagonal locking features.

Attenuators Feature Summary

• Provides controlled signal attenuation for RF circuits
• Supports operation up to 18 GHz frequency range
• Features standard SMA male-to-female interface

Attenuators Applications

• RF test and measurement equipment
• Signal distribution networks
• Wireless communication systems

Attenuators Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as variations exist within the series. Confirm that the 2-watt power rating is sufficient for the intended application environment. Ensure the SMA interface type aligns with existing cabling infrastructure to guarantee proper connectivity.

Attenuators Selection Notes

Select this model when a fixed 4 dB reduction is required at frequencies up to 18 GHz. Consider the 50-ohm impedance match for compatibility with standard RF systems. Evaluate the straight form factor against available space constraints in the assembly layout compared to angled alternatives.

Attenuators Part Context

This component belongs to the family of fixed RF attenuators manufactured by Molex. These devices are engineered to reduce signal amplitude without introducing significant distortion or reflection. The product line supports various attenuation values and connector types to accommodate diverse RF design specifications.

Attenuators Replacement Considerations

Compatible substitutes include other 4 dB SMA fixed attenuators from different manufacturers provided they meet the 18 GHz frequency limit and 50-ohm impedance requirement. Verify mechanical dimensions and mounting style before substitution.
