## Description

desertcart.com: BECEN 10W SMA Attenuator,20db,DC to 3GHz,50 Ohm : Industrial & Scientific

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.
