M3933/25-82N

Overview

The M3933/25-82N is a radio frequency military specification connector manufactured by Amphenol SV Microwave. It belongs to the SMA series and functions as an inline attenuator with a nominal attenuation of 14 dB at 50 ohms impedance. The component supports frequencies up to 18 GHz and operates within a temperature range of -65°C to +165°C. It features a male plug on one side and a female jack on the other, utilizing bulk packaging for distribution.

Feature Summary

• Provides fixed 14 dB signal attenuation in a compact inline form factor
• Supports microwave frequencies up to 18 GHz with 50 ohm impedance
• Constructed for high-temperature environments operating between -65°C and +165°C

Applications

• Microwave signal level reduction in test and measurement equipment
• Attenuation in radar systems requiring MIL-Spec reliability
• Integration into communication subsystems needing precise power control

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm gender configuration and attenuation tolerance. Ensure that the selected variant matches the required frequency range and thermal specifications for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when a fixed 14 dB attenuation is required within the SMA interface standard. Consider the 18 GHz upper frequency limit and the wide operational temperature range when designing for harsh environments. Confirm compatibility with existing male-female mating pairs in the assembly.

Part Context

This component is part of the M3933 series, which defines RF connectors under military specifications. It serves as a specialized passive device within the broader category of microwave interconnects, offering standardized attenuation values for signal conditioning in defense and aerospace applications.

Replacement Considerations

The M3933/25-82S is a screened variant of the same attenuator value. Verify if environmental screening requirements dictate the use of the 'S' suffix over the standard 'N' designation for equivalent performance.
