M3933/30-04N

Overview

The M3933/30-04N is a 50 Ohm RF attenuator from Amphenol SV Microwave, part of the 2.92 mm series. It features SMA single-row module connectors with female-to-female gender configuration. The device operates from DC to 32 GHz with a nominal attenuation of 1.5 dB and a power rating of 2 W. It supports an operating temperature range of -65 °C to +165 °C.

Feature Summary

• Military-grade RF connectorized attenuator design
• High-frequency operation up to 32 GHz
• Extended thermal stability for harsh environments

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement instrumentation
• Microwave communication systems

Procurement Notes

Verify the specific suffix 'N' against procurement requirements, as it denotes non-screened construction compared to screened variants like 'S'. Confirm that the SMA female-to-female interface aligns with system interconnect needs. Ensure environmental specifications meet operational demands given the wide temperature range capabilities documented for this component series.

Selection Notes

Select this model when a low attenuation value near 1.5 dB is required within the 2.92 mm frequency band. The SMA interface provides compatibility with standard test equipment while maintaining high-frequency performance. Consider the 2 W power handling capability for signal conditioning applications in dense RF architectures requiring precise amplitude control.

Part Context

This component belongs to the M3933 family of space attenuators designed by Amphenol SV Microwave. These devices are engineered for precision RF applications, offering reliable performance in demanding environments. The 2.92 mm series ensures consistent impedance and minimal signal reflection across high-frequency ranges.

Replacement Considerations

M3933/30-04S is listed as a parameter-equivalent alternative, differing primarily in screening construction.
