M3933/16-27S

Overview

The M3933/16-27S is a screened RF attenuator manufactured by Amphenol SV Microwave. It operates within the SMA connector series with a 50 Ohm impedance. The device provides an attenuation value of 10.5 dB across a frequency range of 0 Hz to 18 GHz. It features a male-to-female configuration and supports a power rating of 2 W. The component is designed for military specifications and functions reliably within an operating temperature range of -65°C to +165°C.

Feature Summary

• Provides fixed signal attenuation in a screened inline module format
• Supports high-frequency operation up to 18 GHz using SMA interfaces
• Constructed for military specification reliability and environmental stability

Applications

• Military radio systems requiring precise signal level control
• Test and measurement equipment calibration setups
• High-frequency communication infrastructure components

Procurement Notes

Verify the specific attenuation tolerance and screening requirements against the official datasheet before procurement. Confirm that the SMA gender configuration matches the system interface needs. Ensure the operating environment stays within the specified temperature limits. Check for any updated REACH or SVHC compliance documentation relevant to the manufacturing batch.

Selection Notes

Select this model when a fixed 10.5 dB attenuation is required at frequencies up to 18 GHz. The screened design offers protection against external interference compared to non-screened variants. Consider the 2 W power handling capability for high-power applications. Verify compatibility with existing SMA connectors in the assembly.

Part Context

This part belongs to the M3933 family of RF attenuators from Amphenol SV Microwave. These components are engineered for demanding environments, adhering to strict military standards. The series includes various attenuation values and connector types, allowing for flexible integration into complex RF architectures requiring stable signal reduction.

Replacement Considerations

Direct substitutes include other M3933/16 series parts with different attenuation values, such as M3933/16-07S or M3933/16-22S, if the specific 10.5 dB loss is not critical. Ensure any replacement maintains the same SMA gender orientation and screened construction to preserve system integrity.
