M3933/25-58S

Overview

The M3933/25-58S is an RF MIL Spec connector attenuator manufactured by Amphenol / SV Microwave. It features SMA male to female connectors with a 50 Ohm impedance. The device operates within a frequency range of up to 18 GHz and provides a maximum attenuation of 0 dB. It has a power rating of 2 W and functions between -65 C and +165 C.

Feature Summary

• Constructed as a screened RF military specification connector for reliable signal integrity.
• Designed with SMA plug to jack interface configuration for standard interconnect compatibility.

Applications

• RF signal path attenuation in military communication systems
• Test and measurement equipment requiring screened interconnects
• Avionics signal conditioning modules

Procurement Notes

Verify the specific screening requirements against the datasheet, as this model denotes screened construction. Confirm that the zero-decibel specification aligns with the intended circuit design, as it functions primarily as a screened interconnect rather than a signal-reducing component. Ensure environmental ratings meet operational extremes.

Selection Notes

Select this component when screened SMA interconnects are required for MIL Spec compliance. The wide temperature range supports harsh environment deployment. Verify that the 2 W power handling meets system peak power levels. Consider the screened variant over non-screened versions if electromagnetic interference protection is necessary for the application.

Part Context

This part belongs to the M3933 series of RF attenuators and interconnects from Amphenol SV Microwave. The series includes various attenuation values and configurations. The M3933/25-58S specifically represents the screened SMA variant within this product line, distinguishing it from non-screened or different connector type models.

Replacement Considerations

M3933/25-31S is a parameter equivalent screened SMA attenuator with 5 dB attenuation. Verify functional differences before substitution.
