M3933/25-41N

Overview

The M3933/25-41N is an RF MIL Spec connector manufactured by Amphenol SV Microwave. It belongs to the SMA series and functions as a male-to-female attenuator with a 50 Ohms impedance. The component supports a maximum frequency of 18 GHz and provides a maximum attenuation of 41 dB. It operates within a temperature range of -65 C to +165 C.

Feature Summary

• SMA male to female connector configuration
• Fixed high-value signal attenuation
• Military specification compliance
• High-temperature operational capability

Applications

• RF power level reduction in satellite microwave circuits
• Signal conditioning in military communication systems
• Test and measurement equipment calibration

Procurement Notes

Verify the specific suffix 'N' indicates non-screened construction per official documentation. Confirm that the 18 GHz frequency rating and 41 dB attenuation values match the required system specifications. Ensure compatibility with existing SMA interfaces and validate thermal performance against the stated operating limits before integration.

Selection Notes

Select this model for applications requiring precise, fixed attenuation at high frequencies. The SMA interface ensures broad compatibility with standard RF infrastructure. Consider the non-screened variant if shielding is provided externally or is unnecessary for the specific deployment environment.

Part Context

This part is part of the M3933 series, which defines standardized RF attenuators for military and aerospace use. The series includes various attenuation values and connector types, all adhering to strict MIL-Spec requirements for reliability and performance in harsh environments.

Replacement Considerations

Direct substitutes include other M3933/25 variants with different attenuation levels, such as M3933/25-12S or M3933/25-31N. Verify that any replacement matches the 18 GHz frequency limit and SMA gender configuration.
