M3933/30-27N

Overview

The M3933/30-27N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications. It features SMA male-to-female connectors and operates within a frequency range of 0 Hz to 32 GHz. The component provides a nominal attenuation value of 14 dB with a characteristic impedance of 50 Ohms. It supports a maximum power rating of 2 Watts and functions reliably across an operating temperature range from -65°C to +165°C. This inline module is suitable for demanding military and aerospace environments requiring precise signal reduction.

Feature Summary

• Provides fixed 14 dB attenuation for signal level control
• Operates up to 32 GHz frequency range
• Supports 2W power handling capability
• Features SMA male to female interface

Applications

• Military communication systems
• Aerospace test and measurement equipment
• High-frequency signal processing circuits
• RF instrumentation modules

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm connector gender and attenuation tolerance. Ensure that the required operating temperature range aligns with the specified -65°C to +165°C limits. Confirm compliance with relevant environmental standards such as RoHS3 if applicable to your system requirements before finalizing procurement.

Selection Notes

Select this component when a fixed 14 dB attenuation is required in a compact inline module format. Consider the SMA interface compatibility with existing circuit board or cable assemblies. Evaluate the 2W power rating against peak signal levels to prevent damage. The wide temperature range makes it suitable for harsh environment deployments where standard commercial components may fail.

Part Context

This model belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. The series includes various attenuation values and connector configurations tailored for military specifications. These components are engineered for reliability in defense and aerospace sectors, offering consistent performance across extreme conditions compared to general-purpose commercial attenuators.

Replacement Considerations

M3933/30-27S is a parameter-equivalent screened variant offered by Amphenol SV Microwave. Verify mechanical screening requirements and exact attenuation tolerances when substituting between non-screened and screened versions to ensure system integrity.
