M3933/25-47N

Attenuators Overview

The M3933/25-47N is an RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a fixed attenuation value of 21 dB with a tolerance of ±0.7 dB. The device operates within a frequency range of 0 Hz to 12.4 GHz and maintains a 50 Ohm impedance. It features SMA connectors and supports a power rating of 2 Watts. This component is designed as an in-line module suitable for high-reliability applications.

Attenuators Feature Summary

• Fixed 21 dB attenuation with ±0.7 dB tolerance
• Operates from DC to 12.4 GHz
• SMA connector interface for in-line integration
• 2 Watt power handling capability

Attenuators Applications

• RF signal level control in microwave systems
• Test and measurement equipment calibration
• Military and aerospace communication links
• Signal conditioning in radar systems

Attenuators Procurement Notes

Verify the specific suffix 'N' against official datasheets to confirm non-RoHS status and MIL-spec compliance. Confirm SMA gender configuration (male/female) matches system requirements. Check current availability as this item may be subject to long lead times or limited stock due to its specialized nature.

Attenuators Selection Notes

Select this model when a precise 21 dB reduction is required up to 12.4 GHz. Ensure the 2W power rating exceeds peak signal levels. Compare against other M3933/25 variants if different attenuation values like 8dB or 24dB are needed. Verify connector polarity compatibility with existing SMA infrastructure.

Attenuators Part Context

This part belongs to the M3933/25 series of connectorized attenuators. It is distinct from higher-frequency models like the ATT-0550 series which operate up to 26.5 GHz. It differs from lower-frequency variants such as the M3933/25-25N which is limited to 2 GHz. The series is characterized by rugged construction for demanding environments.

Attenuators Replacement Considerations

Direct substitutes include other M3933/25 series parts with similar attenuation, such as M3933/25-34N (8dB) or M3933/25-50N (24dB), though attenuation values differ. Cross-reference with generic SMA attenuators only if military specifications are not mandatory.
