AT-308(40)

Attenuators Overview

The Hirose AT-308(40) is an inline RF attenuator designed for high-frequency signal management. It provides a fixed attenuation value of 8 dB with a nominal impedance of 50 Ohms. The component operates within a frequency range of 0 Hz to 18 GHz and supports a maximum power rating of 1 Watt. It utilizes SMA female-to-female connectors for seamless integration into coaxial transmission lines.

Attenuators Feature Summary

• Provides precise 8 dB signal reduction for RF applications
• Maintains 50 Ohm impedance matching across the operational bandwidth
• Supports frequencies up to 18 GHz using SMA interface
• Handles continuous power loads up to 1 Watt

Attenuators Applications
