Clear signal every time with a perfect 3dB attenuator

Getting a clean and reliable RF signal isn’t just about power — it’s about control. If you’ve ever dealt with signal distortion, mismatch, or unwanted reflections, you already know how important it is to manage signal strength properly. That’s where a 3DB attenuator comes in. It’s a simple tool that solves some of the most frustrating problems in RF setups.

Whether working in a lab, setting up a test bench, or doing field work, using the right attenuator can save time and reduce noise in your system. We offer several high-quality RF attenuators ready to ship fast, so you’re never left waiting.

Here’s why choosing the right attenuator — especially a 3 dB or SMS attenuator — makes a big difference.

Why a 3DB attenuator is the Go-To Choice

A 3DB attenuator is one of the most used types for a reason. It reduces signal power by half, which helps prevent overload in sensitive RF receivers and test equipment. That slight drop in signal can protect your gear and keep everything running smoothly.

• Perfect for signal balancing: This is your go-to if you're working on splitting power between paths or keeping signal levels even across multiple devices.

• Reliable for testing: Testing gear or simulating loss in real-world conditions? This is an easy fix that saves time and money.

• Safe for your equipment: Dropping the signal by 3 dB can be the difference between clean performance and damaging spikes.

We carry attenuators that are made with precision and built for demanding environments. The models come in multiple connector types, including SMA, 2.4mm, and 2.92mm, so you get exactly what you need.

What Makes a SMA Attenuator a Solid Pick

The SMA attenuator stands out for its size, reliability, and solid connection. These are commonly used in high-frequency setups, and we offer models that cover ranges from DC up to 67GHz.

• Compact design: SMA connectors are small but durable, great for crowded workspaces or portable kits.

• Wide frequency range: Our SMA attenuator options handle everything from basic testing to high-frequency designs, giving you flexibility across projects.

• Strong build quality: Brass tri-metal plated bodies offer long-lasting use, especially in lab or field setups with a lot of wear.

You’ll find SMA attenuator models starting at budget-friendly prices without cutting corners on quality.
