M3933/14-10S

Overview

The M3933/14-10S 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 a fixed attenuation of 7 dB and supports a frequency range from DC to 12.4 GHz. It features a male-to-female configuration and has a power rating of 2 W. The unit is designed for military specifications and functions within an operating temperature range of -65°C to +165°C.

Feature Summary

• Provides fixed 7 dB signal attenuation in an inline module format
• Constructed with SMA male-to-female connectors for secure interfacing
• Screened design intended for high-reliability military applications
• Capable of operation across a wide temperature spectrum up to 165°C

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement equipment calibration
• Military communication system signal conditioning

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant required for your application environment. Confirm that the 12.4 GHz upper frequency limit aligns with your system's operational bandwidth. Ensure the 2 W power rating is sufficient for your peak signal levels. Check compatibility with existing SMA mating interfaces before integration.

Selection Notes

Select this component when a precise 7 dB reduction is needed at frequencies up to 12.4 GHz. The screened construction makes it suitable for environments requiring enhanced shielding against interference. Consider the thermal limits if the device will operate near the maximum rated temperature of 165°C.

Part Context

This part belongs to the M3933 series of RF attenuators, which are standardized for military use. The series includes various attenuation values and connector types, such as 2.92mm variants for higher frequencies. This specific model utilizes the widely adopted SMA interface, balancing performance with mechanical robustness for defense and aerospace sectors.

Replacement Considerations

Direct substitutes include other M3933/14 series parts with different attenuation values, such as M3933/14-03N or M3933/14-01N, provided the specific dB value matches the design requirement. Verify that any replacement maintains the same screened status and SMA gender configuration.
