M3933/25-59S

Overview

The M3933/25-59S is a screened SMA male-to-female attenuator manufactured by Amphenol / SV Microwave. It operates within a frequency range of 0 Hz to 18 GHz with a nominal attenuation value of 0.5 dB. The component features a 50 Ohm impedance and supports a power rating of 2 W. Designed for military specifications, it functions reliably between -65 °C and +165 °C. The unit is supplied in bulk packaging.

Feature Summary

• Screened construction for enhanced electromagnetic interference protection
• Military specification compliance ensuring rugged reliability
• Fixed low-value attenuation for precise signal level control

Applications

• RF test and measurement instrumentation
• Defense and aerospace communication systems
• High-frequency circuit calibration setups

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant when sourcing replacements. Confirm that the 0.5 dB attenuation value matches the required system design parameters. Ensure the SMA gender configuration aligns with existing connector interfaces. Validate that the operating temperature range meets environmental requirements.

Selection Notes

Select this model for applications requiring minimal signal loss within the 18 GHz bandwidth. Consider the screened housing if EMI shielding is critical. Verify compatibility with standard SMA mating connectors. Assess whether the fixed 0.5 dB attenuation suits the specific gain or loss budget of the RF chain.

Part Context

This part belongs to the M3933 series of RF MIL Spec Connectors. It utilizes the SMA interface standard for high-frequency performance. The product line includes various attenuation values and connector configurations. It is designed for demanding environments requiring strict adherence to military standards.

Replacement Considerations

M3933/25-59N is the non-screened equivalent. Other series members include M3933/25-12S and M3933/25-69S for different attenuation levels.
