AT-120-WP1(40)

Attenuators Overview

The AT-120-WP1(40) is a fixed RF attenuator manufactured by Hirose Electric Co Ltd. It features SMA connectors and provides a nominal attenuation of 20 dB. The component operates within a frequency range of DC to 18 GHz and has an impedance of 50 ohms. It is rated for a maximum power handling of 1 W. The device functions within a temperature range of -10°C to +65°C.

Attenuators Feature Summary

• Provides precise signal attenuation via SMA plug-to-jack interface
• Operates effectively across a broad frequency spectrum up to 18 GHz
• Designed for stable performance in standard environmental conditions

Attenuators Applications

• RF signal path attenuation in test and measurement equipment
• Signal conditioning in wireless communication systems
• Impedance matching networks requiring fixed loss elements

Attenuators Procurement Notes

Verify the specific suffix WP1 against official Hirose documentation to confirm physical dimensions and mating compatibility. Ensure the required attenuation value matches the 20 dB specification. Confirm that the operating frequency and power ratings align with system requirements before procurement.

Attenuators Selection Notes

Select this component when a fixed 20 dB loss is required at frequencies up to 18 GHz. Ensure the SMA connector type matches the circuit board or cable assembly. Verify that the 1 W power rating is sufficient for the application signal levels.

Attenuators Part Context

This part belongs to the Hirose AT series of fixed attenuators. These components are designed to provide consistent signal reduction in RF circuits. The series offers various attenuation values and connector types to suit different high-frequency applications.

Attenuators Replacement Considerations

Check for direct substitutes within the Hirose AT series with identical 20 dB attenuation and SMA interfaces. Verify that any alternative component meets the same 18 GHz frequency limit and 50 ohm impedance specifications.
