## Overview

The BECEN 10W SMA Attenuator offers precise 40dB signal reduction across a wide DC to 3GHz frequency range, handling up to 10 Watts of power with a low VSWR of ≤1.20. Built with a sturdy metal body and integrated heatsink, it ensures reliable performance and heat management during extended use. Featuring SMA male input and female output connectors, it’s ideal for professionals needing to safely test transmitters and receivers without risking equipment damage.

## Description

10W DC-3GHz SMA male to SMA female ( male is input and female is output) VSWR ≤ 1.20,50 Ohm (1-10dB)±0.5dB,(15-40dB)±1dB

Review: Excellent low power attenuator, very good when direct testing transmitter/receiver - Excellent lower power attenuators allowing the output of 10Watt transmitters to be reduced to a level that permits the attenuator output to be connected to a receiver or spectrum analyzer at a low enough level to avoid damage. It's bulky and heavy, though much less so than a 100W model. It should reduce the transmitter output by two orders of magnitude, 0.05Watts from a 5Watt source. It helps to have lower power cascaded "tuning" attenuators to adjust as necessary. You probably shouldn't hang it on a handy-talky (HT) as it's weight isn't something the HT is designed to have on the antenna connector. So, best used on a flat surface.Any heat from the attenuation will be distributed through the built-in heatsink. It would be best to use with a little care on surfaces but 10 Watts and the circular heatsink should mean not much heat transfers even during long transmissions. It's useful to have a variety of short connector cables to attach to other devices, this has SMA male input and SMA female output.
Review: I’ve bought several of these now, different db,s - A great product good solid engine engineering. I’m sure it will last a lifetime.
