Applications

• RF signal path attenuation
• Test and measurement equipment
• Communication systems

Procurement Notes

Verify current availability status as this component may be out of stock or discontinued. Confirm specific manufacturing lot requirements and lead times directly with the manufacturer or authorized distributors, as supply chain conditions for military-grade components can vary significantly.

Selection Notes

Select this part when a precise 21 dB reduction is required at frequencies up to 2 GHz. Ensure the system impedance matches the 50 Ohm specification. Consider the 2 W power rating against peak signal levels to prevent thermal damage during operation.

Part Context

This component belongs to the M3933/25 series of coaxial attenuators. These parts are designed for high-reliability applications requiring stable attenuation characteristics over temperature variations. The series typically features robust construction suitable for demanding environments.

Replacement Considerations

Check for direct cross-reference part numbers from other manufacturers offering identical 21 dB SMA attenuators with matching 2 GHz bandwidth and 50 Ohm impedance. Verify mechanical footprint compatibility before substitution.
