Product Bulletin – Integrate RF Surge and Lightning Protection Without Paying a Size or Weight Penalty!

The Neverending Quest For Size Reduction

As with most technologies, RF and Wireless system design is an ever-changing and shifting world.  As certain technologies or RF bands become popular, others fade away.

However, the one ever-present force on the industry is the steady, but relentless, push towards smaller size and better integration over time.

Lightning/Surge Protection at the PCB Level?

Here at NexTek we understand the desire to bring things into the box, or even all the way onto the Radio PCB… However, we also know that Lightning Transients contain too much energy to deal with safely at the PCB Level… Trace widths, ground place areas, and the components themselves all become limiting factors that will prevent complete and effective protection.

Given this reality, the last place where it is reasonable and safe to protect against Lightning or other Surge events is at the radio’s box or chassis level.  By replacing the normal I/O connector with a protected version, designer can ensure that they have high-performance protection without paying any significant size or weight penalty.  As long as the radio’s chassis is grounded well, the bulk of the Transient Energy will be drained safely to ground before entering the box and/or the PCB itself.

It may still be advisable to install some simple protection on the PCB, but only for final clean-up…Something like a small Protection Diode coupled with a DC Blocking Capacitor (if possible for your application) would provide plenty of protection against any residual energy that gets past the Protected I/O Connector.

Maximum Protection in the Minimum Amount of Space

Below, you can see an array of our Ultra-Compact protection options…  They all include high-performance lightning protection, and are available in a wide variety of connector configurations on both the Input and Output side.compact-arrestors

Outside Connector Options – Type N, TNC, SMA

Inside Connector Options – SMA, MMCX, RG188, RG316, and more!

Threat Types – Lightning, Static (ESD), and EMP

Ultra Compact Protection Product Bulletin – Post



Compact Surge Protection – New Product Bulletin Available!


We are happy to announce the recent release of a brand-new two-page bulletin and brochure, featuring our range of compact high-performance arrestors.  Whether you are working on a new design, or trying to retrofit something onto an existing one…these ultra-small options are ideal for any application where size is a critical design factor.

Instead of trying to add some (likely inadequate) transient protection on-board, or having to go all the way to a traditional external arrestor mounted somewhere on the cable run…It is now possible to integrate world-class protection against Lightning, Static (ESD) or High-Speed EMP into a bulkhead connector that will easily replace most existing I/O feedthrus!

With the wide array of connector options and frequency ranges available, you should be able to find a solution for any application.  Learn more and download the new Product Bulletin by following the jump below;

Revised PTC-F02 – Datasheet Now Available

Special Announcement – PTC-F02 Design Revision and Updated Datasheet


PTC-F02


For those customers who are currently using or considering the use of our 75Ohm F Type Arrestor [P/N PTC-F02], we have an updated datasheet and drawings to share with you!

Up until recently, the PTC-F02 has been one of our oldest designs.  Developed in partnership with a large Internet Service Provider in the 1990s, this unit provided cutting-edge performance for the time and remains the highest performing F-Type lightning arrestor available.  However, we wanted to incorporate some of the modern design and manufacturing techniques that we have developed since this unit was first made, and as a result we have given it a complete revision and update.

All outer dimensions are generally the same, and all of the specific thread sizes and diameters remain identical to the original. In other words… you will not notice a difference, and instead you will continue to experience class-leading protection and performance for 75Ohm TV/Cable/Satellite or Intermediate Frequency (IF) line applications.

Check out the updated datasheet below!

Content Spotlight – Optimized Lightning Protection for High Frequencies (4-6GHz and Beyond)

Wireless Installation - Building Rooftop

This week’s featured article is a Technical Article previously published in Interference Technology magazine.  This in-depth article contains details and information about providing Lightning and Surge protection for coaxial and RF applications operating in the 4 to 6GHz range.

The widely used Public Safety (4.9GHz), UNII (5.6GHz), and ISM (5.8GHz) band applications all operate within this frequency window, so there are a multitude of applications and users around the world.

High-Frequency applications within this range can be treated different in terms of the Protection Design and Technology used on this type of system.  For example, the relatively high frequency range means that Quarter Wavelength Stub arrestors are ideal protectors for any application where DC Pass is not required!

New Technical Note – Transient Testing GDT-Based Surge Arrestors – Information and Details

Full Scale Lightning Testing - Technical Note GDT Transient Testing


Would you like to know more about performing Transient Testing on Gas Discharge Tube based arrestors?  More specifically, testing arrestors against the common Lightning-derived industry-standard 1.2×50µs/8×20µs Voltage/Current Waveform using commonly available equipment to 6kV/3kA surge current levels.

The 1.2×50µs/8×20µs standard is meant to replicate conditions and energy levels that you can expect during an Indirect Lightning Strike, i.e. one where there is a nearby Lightning strike but without any direct attachment to the cable being test.  These are also known as Induced or Coupled Lightning transients, because the lightning energy does not need to direct connect or attach to the coaxial cable’s center conductor for that conductor to be carrying Lightning surge energy.

If you’d like to learn more about how to perform this testing, and even some insights about how a Gas Discharge Tube responds to this type of transient event… check out the brand-new Technical Note/White Paper posted today!

Using COTS Arrestors in Defense Applications – Article Spotlight

This week’s featured content is an article written by NexTek’s VP of Engineering, George Kauffman, and published in Defense Electronics magazine.

As military and defense programs demand more efficiency and value for the dollar, many Commercial-Off-The-Shelf components and solutions are being used in defense systems and equipment. Not only does the use of COTS parts help keep development costs and time to a minimum, it is possible to make a system that is just as reliable and high-performance as a fully custom-engineered solution.
