M3933/30-14S

Overview

The M3933/30-14S is a fixed attenuator module manufactured by Amphenol SV Microwave, designed for high-frequency RF applications. It operates within a frequency range of 0 Hz to 32 GHz and provides a nominal attenuation value of 6.5 dB. The component features SMA male-to-female connectors and maintains a characteristic impedance of 50 Ohms. It is rated for a maximum power handling capacity of 2 Watts. The unit is constructed as an in-line module suitable for integration into shielded or unshielded RF circuits requiring precise signal level reduction.

Feature Summary

• Provides fixed 6.5 dB attenuation across the DC to 32 GHz bandwidth
• Utilizes robust SMA connector interface for reliable interconnection
• Engineered for high-power handling up to 2 Watts in inline configurations

Applications

• RF test and measurement instrumentation signal conditioning
• Satellite communication system power level adjustment
• Microwave circuit calibration and reference standards

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm shielding status and exact attenuation tolerance. Ensure that the SMA connector gender configuration matches the system requirements. Confirm RoHS compliance and environmental operating temperature ranges prior to integration. Cross-reference the part number with current datasheets to validate availability and manufacturing revisions.

Selection Notes

Select this component when a fixed 6.5 dB attenuation is required within the 32 GHz operational limit. The SMA interface dictates compatibility with existing connector systems. Consider the 2W power rating relative to the maximum signal levels in the application path. Evaluate the physical form factor for space-constrained PCB or panel mount implementations.
