Bird's 150 W RF attenuators provide reliable RF signal attenuation for testing, measurement, and system integration. Available in multiple series with a range of attenuation values and connector configurations to meet your application requirements.
Choose the Right 150 W Attenuator
DC to 3 GHz | Bi-Directional
150‑A Series
Best for Bench & Laboratory Testing
Same-side connectors simplify connections between instruments and devices under test, making the 150-A Series ideal for engineering labs, production testing, and troubleshooting.
DC to 2.4 GHz | Bi-Directional
150‑SA Series
Best for Inline Installations
Opposite-end connectors provide a natural signal path through the attenuator, making installation easier in permanently integrated RF systems and production equipment.
DC to 2.4 GHz | Directional
150-WA Series
Most Economical for One-Way Signal Paths
Designed for applications where RF power flows in a single direction. By eliminating bi-directional capability, the 150-WA Series provides dependable attenuation at the lowest cost in the 150 W family.
