M3933/25-29S

Overview

The M3933/25-29S is a screened RF MIL Spec connectorized attenuator manufactured by Amphenol SV Microwave. It utilizes the SMA interface with a male-to-female configuration and maintains a 50 Ohm impedance. The component operates within a frequency range up to 18 GHz and provides a maximum attenuation of 3 dB. It features a bulk packaging format and supports a power rating of 2 W. The unit is designed for high-reliability environments, functioning between -65°C and +165°C.

Feature Summary

• Screened construction for enhanced environmental protection
• SMA male-to-female inline module design
• Military specification compliance

Applications

• RF signal conditioning in military communication systems
• Test and measurement instrumentation requiring precise attenuation
• High-frequency electronic circuits operating up to 18 GHz

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant during procurement. Confirm that the 3 dB attenuation value aligns with system requirements. Ensure compatibility with SMA connectors and 50 Ohm impedance standards. Check for military specification compliance if required for the application environment.

Selection Notes

Select this model when a screened SMA attenuator is required for frequencies up to 18 GHz. Consider the 3 dB attenuation level and 2 W power handling capabilities. Evaluate the temperature range suitability for extreme operational conditions. Compare against non-screened variants if environmental sealing is not critical.

Part Context

This component belongs to the M3933 series of RF MIL Spec Connectors. It is part of the SMA product line offered by Amphenol / SV Microwave. The series includes various attenuator values and configurations for different frequency ranges and screening requirements.

Replacement Considerations

M3933/25-29N is a parameter-equivalent non-screened alternative from the same manufacturer.
