M3933/25-34S

Overview

The M3933/25-34S is a screened RF attenuator manufactured by Amphenol SV Microwave, designed for military specifications. It features SMA male-to-female connectors with a 50 Ohm impedance and operates up to 18 GHz. The component provides a fixed attenuation of 8 dB and has a power rating of 2 W. It functions within a temperature range of -65°C to +165°C and is supplied in bulk packaging.

Feature Summary

• Screened construction for enhanced environmental protection
• Fixed 8 dB attenuation value
• Military specification compliance

Applications

• RF signal level control in military systems
• Test and measurement equipment
• Communication subsystems requiring precise signal reduction

Procurement Notes

Verify the specific screening requirements against project standards before procurement. Confirm that the 8 dB attenuation value aligns with system design needs. Ensure compatibility with SMA connector interfaces. Check lead times as production cycles may vary. Validate operating temperature ranges for extreme environment applications.

Selection Notes

Select this model when a fixed 8 dB attenuation is required at frequencies up to 18 GHz. Consider the screened variant if environmental shielding is necessary. Ensure the 2 W power rating meets system power levels. Verify SMA gender configuration matches the circuit topology.

Part Context

This component belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. It is part of a family offering various attenuation values and connector types. The series supports high-frequency applications requiring stable performance under military conditions.

Replacement Considerations

Compatible substitutes include other M3933/25 variants with different attenuation values, such as M3933/25-31S or M3933/25-12S, provided the attenuation difference is acceptable. Non-screened versions like M3933/25-31N may be used if shielding is not critical.
