M3933/25-36S

Overview

The M3933/25-36S is a screened SMA male-to-female fixed attenuator manufactured by Amphenol SV Microwave. It operates within a frequency range of DC to 18 GHz and provides a nominal attenuation of 36 dB. The component features a 50 Ohm impedance and supports a power rating of 2 W. It is designed for military specifications, with an operating temperature range spanning from -65°C to +165°C. The unit utilizes SMA connectors and is packaged in bulk.

Feature Summary

• Screened construction for enhanced signal integrity
• Military specification compliance for rugged environments
• Fixed attenuation value for precise signal control

Applications

• RF test and measurement equipment
• Military communication systems
• Aerospace electronic assemblies

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant when sourcing replacements. Confirm that the required attenuation matches the 36 dB specification exactly, as other suffixes denote different values. Ensure the procurement channel sources genuine Amphenol SV Microwave components to guarantee MIL-spec compliance and temperature ratings. Check datasheets for any recent manufacturing updates.

Selection Notes

Select this model only when a high attenuation value near 36 dB is required within the 18 GHz bandwidth. Consider the screened design if shielding against external interference is critical for the application. Verify that the SMA connector gender combination (Male to Female) aligns with the system interconnect requirements. Ensure the 2 W power handling capacity meets the operational signal levels.

Part Context

This part belongs to the M3933 series of RF fixed attenuators from Amphenol SV Microwave. The series offers various attenuation values and connector types, including SMA and 2.92mm. The M3933/25-36S specifically addresses high-attenuation needs in military-grade RF circuits, distinguishing itself from lower attenuation variants like the M3933/25-31S or non-screened versions.

Replacement Considerations

• M3933/25-36N (Non-screened variant)
• M3933/25-31S (Different attenuation value)

FAQ

What is the difference between the M3933/25-36S and M3933/25-36N?

The primary difference is the screening. The 'S' suffix denotes a screened attenuator, while the 'N' suffix indicates a non-screened version. Both share the same 36 dB attenuation and SMA interface.

Does the connector configuration allow for direct mating with standard SMA cables?

Yes, it features an SMA Male connector on one side and an SMA Female connector on the other, allowing it to bridge components with complementary SMA interfaces.
