AT-405(40)

Attenuators Overview

The AT-405(40) is a connectorized RF attenuator from the Hirose AT-400 series, designed for signal reduction in radio frequency circuits. It features N-type male-to-female connectors and maintains a 50 Ohm impedance. The component provides a fixed attenuation of 5 dB with a power rating of 2 W. It operates within a frequency range up to 13 GHz and functions reliably between -10°C and +65°C.

Attenuators Feature Summary

• Fixed 5 dB attenuation for precise signal level control
• N-type male to female interface configuration
• 50 Ohm impedance matching for RF systems
• RoHS compliant construction

Attenuators Applications

• RF test and measurement equipment
• Wireless communication system calibration
• Signal path attenuation in receiver chains

Attenuators Procurement Notes

Verify the exact suffix (40) against official datasheets to confirm connector orientation and specifications. Confirm current availability status as distribution channels may list obsolete or discontinued inventory. Ensure compliance with RoHS requirements if applicable to your manufacturing process.

Attenuators Selection Notes

Select this model when a fixed 5 dB reduction is required at N-type interfaces. Verify that the 2 W power handling meets system peak power levels. Check operating temperature limits (-10°C to +65°C) against environmental conditions. Ensure frequency requirements do not exceed the 13 GHz upper limit.

Attenuators Part Context

This part belongs to the Hirose AT-400 series of low-profile connectorized attenuators. These components are engineered for compact integration into RF assemblies requiring stable attenuation characteristics across wide bandwidths.
