M3933/30-31S

Overview

The M3933/30-31S is a connectorized RF attenuator manufactured by Amphenol SV Microwave. It features SMA male to female connectors and operates within a frequency range of 0 Hz to 40 GHz. The component provides a fixed attenuation value of 31 dB at a 50 Ohm impedance. It supports a power rating of 2 W and functions reliably across an operating temperature range from -65°C to +165°C.

Feature Summary

• Provides fixed 31 dB attenuation for signal level control
• Supports high-frequency operation up to 40 GHz
• Features robust SMA male-to-female interconnect configuration

Applications

• High-frequency test and measurement instrumentation
• Defense and aerospace radar systems
• Satellite communication equipment

Procurement Notes

Verify the specific attenuation tolerance and VSWR values against the official manufacturer datasheet before integration. Confirm that the SMA connector gender orientation matches the system interface requirements. Ensure the thermal management design accommodates the 2 W power rating within the specified temperature limits to maintain performance stability.

Selection Notes

Select this model when a precise 31 dB reduction is required in the 40 GHz band. Compare with other M3933 series variants if different attenuation levels or connector types are needed. Consider the screened versus non-screened versions based on EMI shielding requirements for the specific application environment.

Part Context

This component belongs to the M3933 series of military specification RF attenuators. The series offers various fixed attenuation values and connector configurations designed for rugged environments. It complements other Amphenol SV Microwave interconnect solutions for complete RF chain assembly.

Replacement Considerations

M3933/30-31N is a parameter-equivalent alternative within the same product line.
