M3933/25-62N

Overview

The M3933/25-62N is a coaxial RF attenuator manufactured by Amphenol SV Microwave. It utilizes SMA male-to-female connectors and operates within a frequency range of DC to 18 GHz. The component provides a nominal attenuation value of 2 dB at a characteristic impedance of 50 Ohms. It supports a maximum power rating of 2 W and functions reliably across an operating temperature range from -65 °C to +165 °C.

Feature Summary

• Provides precise signal attenuation for high-frequency RF applications
• Features robust SMA connector interface for secure mating
• Designed for wide operational temperature environments

Applications

• RF test and measurement instrumentation
• Military and aerospace communication systems
• Wireless infrastructure signal conditioning

Procurement Notes

Verify the specific suffix 'N' against official Amphenol documentation to confirm material composition and plating specifications. Ensure that the required attenuation tolerance and power handling capabilities align with the system design requirements before procurement. Cross-reference the datasheet for any updates regarding RoHS compliance status or environmental certifications.

Selection Notes

Select this model when a low attenuation value is required for SMA interfaces up to 18 GHz. Consider the 2 W power rating and extended temperature range for demanding environments. Evaluate alternative models in the series if higher attenuation values or screened variants are necessary for specific shielding requirements.

Part Context

This component belongs to the M3933 series of connectorized attenuators, designed for military and industrial standards. It complements other variants such as the M3933/25-62S, which offers similar electrical performance but may differ in screening or material specifications. The series ensures compatibility with standard SMA infrastructure while maintaining high reliability.

Replacement Considerations

M3933/25-62S is a parameter-equivalent substitute offering identical electrical characteristics. Verify mechanical screening requirements and material differences between the 'N' and 'S' suffixes before substitution.
