M3933/14-08N

Overview

The M3933/14-08N is a radio frequency attenuator manufactured by Amphenol SV Microwave. It features SMA male to female connectors and operates within a frequency range of DC to 12.4 GHz. The component provides an attenuation value of 4 dB at a system impedance of 50 Ohms. It is designed for non-screened applications and supports a maximum power rating of 2 W. The unit functions reliably across an operating temperature range from -65 °C to +165 °C.

Feature Summary

• Provides precise signal attenuation in RF circuits using SMA interconnects
• Engineered for high-temperature stability up to 165 °C
• Supports continuous power handling of 2 W at 50 Ohms

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement instrumentation
• Military communication systems requiring MIL-spec components

Procurement Notes

Verify the specific suffix 'N' indicates the non-screened configuration as documented. Confirm the 4 dB attenuation value matches the design requirement. Ensure the SMA gender combination aligns with the system interface. Validate that the 12.4 GHz upper frequency limit meets the operational bandwidth needs. Check for RoHS compliance status if required by the project specifications.

Selection Notes

Select this model when a fixed 4 dB reduction is required in the 12.4 GHz band. The non-screened construction suits applications where external shielding is provided or unnecessary. The wide temperature range allows deployment in harsh environments. Ensure the 2 W power rating exceeds the maximum expected signal level to prevent damage.

Part Context

This part belongs to the M3933 series of RF military specification connectors. The series includes various attenuator values and connector types such as SMA and 2.92mm. These components are designed for high-reliability applications in aerospace and defense sectors. The manufacturer produces both screened and non-screened variants within this family.

Replacement Considerations

M3933/14-07N offers a 2 dB attenuation option within the same SMA series. M3933/25-62N provides similar functionality but operates up to 18 GHz. Verify connector compatibility and attenuation requirements before substituting.
