M3933/16-46S

Overview

The M3933/16-46S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides an attenuation value of 20.5 dB with a 50 Ohm impedance and a 2W power rating. The device operates within a frequency range of 0 Hz to 18 GHz and utilizes SMA connectors in an inline module configuration.

Feature Summary

• Compliant with MIL-DTL-M3933 military specifications for high reliability
• Designed for stable signal attenuation in demanding environments
• Features robust SMA connector interface for secure integration

Applications

• Military electronic systems requiring qualified components
• Aerospace communication equipment
• Test and measurement instrumentation
• Harsh environment RF circuitry

Procurement Notes

Verify the specific suffix 'S' against official datasheets to confirm material and plating specifications, as suffixes often denote critical manufacturing variations. Ensure compatibility with MIL-DTL-M3933 standards if military qualification is required. Confirm RoHS status, as these components may not be compliant. Validate frequency and power ratings against system requirements before procurement.

Selection Notes

Select this component when a precise 20.5 dB attenuation is needed at 50 Ohms up to 18 GHz. Consider the SMA interface and inline form factor for PCB or cable assembly integration. Evaluate thermal management capabilities given the 2W power rating. Compare against other M3933/16 variants if different attenuation values are suitable for the design.

Part Context

This part belongs to the M3933/16 series of fixed attenuators from Midwest Microwave, a brand under Cinch Connectivity Solutions. The series offers various attenuation values while maintaining consistent electrical performance and mechanical interfaces across the product line for modular RF design flexibility.

Replacement Considerations

Check for direct cross-references within the M3933/16 series for alternative attenuation values. Verify equivalent parts from other manufacturers holding MIL-DTL-M3933 qualification. Ensure pinout and connector gender match exactly to avoid physical incompatibility.
