Fixed Attenuators are usually connectorized or available in a surface mount package. They are passive attenuators that provide a fixed attenuation level and have a number of attenuation levels available.

Fight the Power with an Attenuator!

No Comments 20833 Views0

All devices require a certain amount of energy, but sometimes you are working with multiple devices that have various power requirements. This can create a difficult situation, unless you have a Coaxicom attenuator!

An attenuator is the opposite of an amplifier; it reduces the power between connections, making low power instruments compatible with its higher powered counter parts.

The reasons are clear why you should make sure you have the proper attenuators in your arsenal of connections and adapters. You never want to run the risk of damaging an instrument by delivering an excessive surge.  Too much power can ruin an entire piece of very expensive hardware. You also don’t always want to buy new often costly cable connections rated for less power.

Bottom line, an attenuator serves as both a long or short term solution and will save money along the way.

Coaxicom attenuators are made in the U.S.A. using top grade materials. By using a quality and reliable attenuator, you can maximize the performance of your equipment without having to stock up on multiple cables and other components.

There are myriad attenuator types to choose from, so make certain you are knowledgeable on the power specs for your instruments. If you need a little help, Coaxicom engineers are available and will collaborate to solve any issue or answer any question.

Additional products include attenuator kits, as well as DC blocks, GPO, flange mount and Type N attenuators. Coaxicom also offers attenuators to 300-watts.

Coaxicom Praises SwRI’s Advancements in Mobile Autonomous Robotics Technology.

Comments off 1609 Views0

San Antonio – June 14, 2016 – (www.swri.org/) – Southwest Research Institute (SwRI), a leading developer of high performance automated driving algorithms and unmanned systems, is celebrating the 10-year anniversary of its Mobile Autonomous Robotics Technology Initiative during the recent Eurosatory trade show.

Since 2006, SwRI has automated 15 vehicle platforms — from Class VIII tractor trailers and tactical military vehicles to passenger cars and golf carts — with automated driving systems deployed on four continents and seven countries, including Afghanistan.

“Our unique unmanned systems technologies enable automated vehicle deployment in support of military troops and support personnel in a variety of environments around the world,” said Ryan Lamm, R&D director in SwRI’s Automation and Data Systems Division.

At Eurosatory, SwRI will demonstrate technologies that enable reliable perception of humans and roadway obstacles in addition to showcasing algorithms for traversing roadways without GPS.

SwRI’s modular perception systems detect and classify humans, vehicles, and other objects with dynamic scene understanding of complex environments for roadway and off-road applications.

SwRI also will display its patented Ranger localization solution. A 2015 R&D 100 innovation award winner, Ranger enables precise navigation for automated vehicles by utilizing ground-facing cameras and custom SwRI algorithms. The system images the unique “fingerprint” of road surfaces. Algorithms match thousands of distinguishing ground features, such as aggregate, cracks and road markings, to corresponding features collected and stored in a map.

Its camera-based approach with controlled illumination allows for precise automated driving within 2 centimeters, similar to the most accurate (and most expensive) GPS systems, during daytime or night, and in rain and foggy weather conditions. Ranger also operates in areas where GPS has poor performance or fails completely, offering custom capability for military and commercial fleet vehicles.

“Ranger offers the defense sector numerous advantages in operational capability for deployment of unmanned assets in remote locations where GPS is disabled or unavailable,” said Dr. Kristopher Kozak, a principal engineer in SwRI’s Automation and Data Systems.

Why 50 Ω Connectors?

Comments off 2558 Views0

All over the world, the predominant impedance for RF/microwave coaxial transmission lines and connectors is 50 Ω. Here is why….

50 ohm stdThe theoretical impedance for minimum attenuation is 77.5 Ω while the maximum power transfer is 30 Ω. The average of these two impedances is 53.75 Ω (rounded off to 50 Ω). Therefore, 50 Ω is a compromise between the minimum attenuation and maximum power transfer in a coaxial transmission line, and that is why it was selected. There are connectors available with other impedances, the next most popular impedance being 75 Ω (approximate minimum attenuation performance) that is in fairly wide use internationally and in long line communication systems.
