M3933/30-32N

Overview

The M3933/30-32N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications up to 40 GHz. It features SMA male-to-female connectors and maintains a 50 Ohm impedance. The component provides a nominal attenuation of 19 dB with a power rating of 2 W. It operates within a temperature range of -65°C to +165°C and is packaged in bulk.

Feature Summary

• Supports frequency ranges up to 40 GHz for wideband signal processing
• Constructed with SMA male-to-female interface for standard interconnect compatibility
• Rated for operation at temperatures up to +165°C for harsh environment reliability

Applications

• Satellite communication systems requiring precise signal level control
• Microwave circuit testing and measurement setups
• Defense and aerospace radar subsystems

Procurement Notes

Verify the specific datasheet version for the M3933/30-32N to confirm exact electrical tolerances and mechanical drawings. Ensure the SMA connector gender matches the system requirements, as variations exist within the series. Confirm compliance with RoHS3 standards if required for the final assembly.

Selection Notes

Select this model when a fixed 19 dB attenuation is required in the 40 GHz band. Compare against screened variants like the M3933/30-32S if shielding is necessary. Verify that the 2 W power handling meets the peak and average power demands of the transmission line.

Part Context

This part belongs to the M3933 series of space-grade attenuators from Amphenol SV Microwave. These components are engineered for satellite microwave circuits, offering DC to 40 GHz performance. The series includes various attenuation values and connector configurations to support diverse RF power management needs.

Replacement Considerations

The M3933/30-32S is listed as a parameter-equivalent alternative. Verify if the screened construction of the 'S' suffix is acceptable or if the non-screened 'N' version is strictly required for the application.
