M3933/16-23N

Overview

The Amphenol SV Microwave M3933/16-23N is a military specification RF attenuator featuring SMA connectors. It provides a nominal attenuation of 6.5 dB with a 50 Ohm impedance. The component operates within a frequency range up to 18 GHz and supports a power rating of 2 Watts. Designed for rugged environments, it functions between -65°C and +165°C. This screened unit utilizes bulk packaging.

Feature Summary

• Provides precise signal attenuation via SMA interface
• Screened construction for environmental protection
• Capable of high-power operation in extreme temperatures

Applications

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

Procurement Notes

Verify the specific screening status and connector gender configuration against official datasheets prior to ordering. Confirm that the 6.5 dB attenuation value aligns with system requirements. Ensure compatibility with existing SMA mating interfaces and validate thermal performance specifications for the intended operating environment.

Selection Notes

Select this component when a fixed 6.5 dB attenuation is required at frequencies up to 18 GHz. Consider the screened variant for applications demanding enhanced environmental resistance. Verify that the 2 Watt power handling capacity meets peak signal levels. Ensure the SMA male-to-female or female-to-male orientation matches the circuit topology.

Part Context

This part belongs to the M3933 series of space-grade attenuators designed by Amphenol SV Microwave. These components are engineered for satellite and aerospace applications requiring reliable RF power control. The series offers various attenuation values while maintaining consistent 50 Ohm impedance and wide temperature tolerance across the SMA platform.

Replacement Considerations

Cross-reference other M3933 series variants for different attenuation values. Verify equivalent MIL-spec compliance from alternative manufacturers if supply constraints exist. Ensure replacement parts maintain identical SMA connector genders and screening classifications.
