M3933/25-71S

Overview

The Amphenol SV Microwave M3933/25-71S is a screened RF attenuator designed for precision signal control in microwave applications. It features SMA male to female connectors and maintains a 50 Ohm impedance. The component operates within a frequency range of 0 Hz to 18 GHz, providing a fixed attenuation value of 6.5 dB. This inline module is constructed to withstand high thermal environments, with a maximum operating temperature of +165°C.

Feature Summary

• Provides precise 6.5 dB signal attenuation for microwave systems
• Features SMA male to female connector interface
• Designed for operation up to 18 GHz frequency range
• Screened construction for enhanced environmental reliability

Applications

• Microwave signal conditioning
• Precision signal control in RF systems
• High-frequency test and measurement equipment

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant when sourcing replacements. Confirm that the SMA connector gender order matches the male-to-female configuration required by your circuit design. Ensure the 18 GHz frequency limit aligns with your system's operational bandwidth requirements before finalizing procurement.

Selection Notes

Select this component when a fixed 6.5 dB attenuation is required at frequencies up to 18 GHz. The screened version offers improved performance in noisy environments compared to non-screened variants. Consider the SMA interface compatibility and the +165°C thermal rating if the application involves high-temperature operations or strict military specifications.
