How do I choose between a fixed optical attenuator and a variable optical attenuator (VOA)?

Fixed optical attenuators, like those in this NooElec kit, provide a permanent, precise decibel reduction (such as 1dB, 3dB, or 10dB) to prevent optical receiver overload in permanent link deployments. Variable optical attenuators offer adjustable attenuation across a defined range, making them suitable for optical bench testing, link simulation, and active system balancing.

What is the difference between UPC and APC fiber optic attenuators?

This question is not applicable as these are SMA RF attenuators, not fiber optic attenuators. SMA attenuators connect via SMA connectors, while UPC and APC refer to fiber optic connector polishes.

How to choose the right SMA attenuator for my RF setup?

Select an SMA attenuator based on your required attenuation level (dB), frequency range (up to 6GHz for this kit), power handling (2W max), and connector type (SMA). This NooElec kit offers a range from 1dB to 20dB, ideal for fine-tuning signal levels or protecting sensitive inputs.

Are these NooElec attenuators accurate for sensitive RF testing?

Yes, these NooElec attenuators offer excellent accuracy, with +/- 0.1dB precision up to 3GHz and +/- 0.4dB up to 6GHz. This level of precision is invaluable for accurate signal adjustment and device input protection in test bench environments.

Why choose this product

Engineered for RF Precision

This NooElec kit delivers exceptional accuracy and linear attenuation, vital for sensitive RF testing and device protection. Unlike generic attenuators, these are built for consistent performance across a wide frequency range. The laser-etched values ensure you always have clear, permanent identification, a feature often missing in lower-cost alternatives. Imported directly from authorized US retailers, you receive a genuine product designed to meet stringent specifications, ensuring your projects run smoothly and reliably.

Ideal for Test Bench & Device Protection

This kit is perfect for electronics hobbyists, engineers, and technicians who need reliable signal level control. It's excellent for protecting sensitive receiver inputs from strong signals or for precisely adjusting signal strength in test setups. Consider this kit if you frequently work with RF signals and require accurate, durable attenuation. Skip if you only need a single, specific attenuation value or if your application involves significantly higher power levels than 2W.

How to use

Identify Required Attenuation — Determine the specific dB reduction needed for your application. Select the appropriate attenuator from the kit (1dB, 2dB, 3dB, 6dB, 10dB, or 20dB) based on your signal strength and device input requirements.
Connect SMA Components — Ensure both the signal source and the receiving device have SMA connectors. Screw the chosen attenuator securely onto the signal source output or the device input, ensuring a snug fit to prevent signal leakage.
Verify Signal Level — After connecting the attenuator, measure the signal level at the output to confirm the desired attenuation has been achieved. Re-evaluate and swap attenuators if necessary to meet precise signal requirements for testing or protection.
