Procurement Notes

Verify that the specific suffix 'N' matches the required connector gender and material specifications for your assembly. Confirm compliance with MIL-DTL-M3933 quality standards is mandatory for defense applications. Check current manufacturing status as supply chain conditions may affect availability. Ensure environmental ratings meet operational temperature requirements.

Selection Notes

Select this model when a precise 5dB attenuation value is required between DC and 12.4 GHz. The SMA interface suits standard test and measurement setups. Consider the 2W power handling capability for high-power signal paths. Verify impedance matching to ensure minimal reflection in 50 Ohm systems.

Part Context

This component belongs to the M3933/25 series of fixed attenuators from Midwest Microwave. The series offers various attenuation values while maintaining consistent electrical performance and mechanical form factors.
