RF Attenuators
Bird’s RF attenuators give you precise, reliable control over signal strength—whether you’re testing, troubleshooting, or integrating sensitive components. Built to handle high power and harsh environments, our attenuators help prevent overload, reduce reflections, and maintain system performance without compromise.
Choosing the Right Attenuator:
What to Use - and What to Avoid
Convection-Cooled Attenuators
Passively dissipate heat using ambient airflow.
- Best for: Low to moderate power applications in well-ventilated test environments.
- Avoid if: Operating in enclosed spaces or high-power systems that require active cooling.
Oil-Cooled Attenuators
Use oil for dielectric properties and heat dissipation.
- Best for: High-power, continuous-duty applications where thermal stability is critical.
- Avoid if: Space is limited or handling and maintenance of oil-filled equipment is a concern.

Selecting Attenuators: What Really Matters
RF Power Rating
Determine the maximum RF power your attenuator needs to handle—both average and peak. Overloading an attenuator can lead to overheating, signal distortion, or failure.
- Pro Tip: Always choose an attenuator with a power rating at least 20–30% higher than your expected input to ensure reliability and longevity.
Attenuation Value
Attenuators reduce signal strength by a fixed amount, typically measured in dB (decibels). Choose the attenuation value that best protects your equipment or achieves your signal conditioning goals.
- Pro Tip: Not sure what value you need? Consider using multiple attenuators in series to fine-tune total attenuation — just ensure combined ratings still meet power and frequency requirements.
Frequency Range
Make sure the attenuator operates effectively across your system’s operating frequency. Using an attenuator outside its rated range can introduce reflections or reduce accuracy.
- Pro Tip:
For broadband or multi-frequency applications, select a wideband attenuator to ensure consistent performance across your full spectrum.
What's at Stake
Compromised equipment puts your systems, signals, and results at risk.
In high-power RF environments, there's no room for guesswork. The wrong attenuator can compromise your measurements, damage critical components, or bring your system down altogether.
Bird attenuators are built to protect what matters—your signal, your equipment, and your reputation.
