300 Watt RF Attenuators
Bird's 300 W RF attenuators provide continuous, fixed signal attenuation from DC to 2.4 GHz in a convection-cooled design. Choose between the 300-A and 300-WA Series based on directionality, connector orientation, attenuation value, and system configuration.
Choose the Right 300 W Attenuator
DC to 2.4 GHz | Bi-Directional
300‑A Series
Best for: Bench & Laboratory Testing
Same-side connectors and bi-directional operation provide flexible placement in RF test setups, making the 300-A Series well suited for engineering labs, production testing, and troubleshooting.
DC to 2.4 GHz | Directional
300‑WA Series
Best for: Inline RF Systems
Opposite-end connectors and directional operation provide a defined signal path through the attenuator, making the 300-WA Series well suited for inline RF testing and system integration.
