M3933/14-07S

Overview

The M3933/14-07S is a screened RF attenuator manufactured by Amphenol SV Microwave. It operates within the SMA connector series, providing a nominal attenuation of 2 dB at a characteristic impedance of 50 Ohms. The device supports a frequency range from DC to 12.4 GHz and handles a maximum power rating of 2 W. Designed for military specifications, it functions reliably across an operating temperature range of -65 °C to +165 °C.

Feature Summary

• Screened construction for enhanced signal integrity in demanding environments
• Military specification compliance ensuring reliability under extreme conditions
• SMA interface design facilitating standard interconnect compatibility

Applications

• Satellite communication systems requiring precise RF power control
• Test and measurement instrumentation for high-frequency signal analysis
• Avionics and defense electronics utilizing MIL-Spec components

Procurement Notes

Verify that the specific suffix 'S' denotes the screened variant required for your application, as non-screened versions exist within the same family. Confirm that the 2 W power rating aligns with system thermal constraints. Ensure the SMA gender configuration matches the circuit topology before ordering.

Selection Notes

Select this component when a screened attenuator is necessary to prevent external interference or radiation leakage. The 12.4 GHz upper frequency limit suits applications below Ka-band. Consider the bulk packaging format for integration into custom assemblies rather than pre-packaged solutions.

Part Context

This part belongs to the M3933 series of connectorized attenuators designed for space and military applications. It complements other variants like the M3933/14-07N, differing primarily in shielding requirements. The series offers various attenuation values and connector types to support diverse RF circuit needs.

Replacement Considerations

The M3933/14-07N serves as a direct functional substitute if screening is not required. Other parameter-equivalent options include the M3933/25-62N and M3933/25-62S, though these may differ in physical dimensions or specific military screening standards.
