RF Attenuators
RF Attenuators
RF attenuators from Amphenol RF deliver reliable and precise signal reduction, helping engineers prevent equipment overload, calibrate test setups and manage signal levels across complex RF systems. Offering fixed attenuation in popular SMA and N‑Type interfaces, these attenuators support everything from lab instrumentation to telecom and wireless deployments.
Available with attenuation from 1 dB to 10 dB in SMA and N‑Type formats rated at 2 W, our attenuators are engineered for consistent insertion loss, low VSWR and long-term reliability. Whether you're fine‑tuning a test bench or balancing power across an RF network, these durable and easy‑to‑install components support cleaner, safer system performance.
Features and Benefits
- Fixed attenuation precision: Choose from standard dB values (1, 2, 3, 4, 5, 6, 8, 9, 10) for consistent signal reduction.
- Mechanical durability: Machined housings and plated finishes withstand repeated lab and field use.
- Connector standardization: SMA and N‑Type interfaces ensure broad compatibility with existing systems.
- Signal integrity maintained: Low VSWR protects against reflections, preserving waveform fidelity.
- Power handling: Rated for continuous operation with up to 2 W of RF power.
Key Technical Details
- Impedance: 50 Ω (standard for RF systems).
- Connector types: SMA, N‑Type (both available in fixed dB values) .
- Attenuation range: Fixed from 1 dB to 10 dB (SMA and N‑Type models)
- Typical frequency performance: SMA up to ~18 GHz; N-Type up to ~11 GHz (connector dependent; cable may impact range) .
