AT-112(40)

Attenuators Overview

The AT-112(40) is a low power attenuator manufactured by Hirose Electric Co Ltd. It features an SMA in-line module configuration designed for RF signal applications. The component provides a fixed attenuation value of 12dB with a tolerance of ±1.25dB. It operates within a frequency range of 0 Hz to 18 GHz and supports a maximum power handling capacity of 1 Watt. This part is currently classified as obsolete.

Attenuators Feature Summary

• SMA in-line module construction
• Fixed 12dB attenuation value
• Wideband operation up to 18 GHz

Attenuators Applications

• RF test and measurement equipment
• Signal conditioning circuits
• Communication system testing

Attenuators Procurement Notes

Verify availability status carefully as the AT-112(40) is listed as obsolete. Confirm technical compatibility with existing designs before procurement. Check datasheet specifications for impedance and connector type accuracy. Ensure replacement strategies are evaluated if new production is required.

Attenuators Selection Notes

Select this component only when a fixed 12dB attenuation at 18 GHz is required. Verify SMA interface compatibility with system cabling. Consider the 1W power limit for thermal management. Evaluate alternative active or adjustable attenuators if variable control is needed.

Attenuators Part Context

This component belongs to the Hirose Electric RF attenuator product line. It serves as a passive device for reducing signal amplitude in high-frequency circuits. The SMA interface ensures standard connectivity for laboratory and industrial RF setups.

Attenuators Replacement Considerations

No public confirmed substitute part numbers are available. As the part is obsolete, engineers must evaluate generic SMA attenuators with matching 12dB attenuation, 18 GHz bandwidth, and 1W power rating for functional equivalence.
