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

If you are looking for coaxial protection that does not cost you any more space and weight than absolutely necessary, perhaps because you’d prefer to integrate protection into the Radio Chassis itself, then you really have to check out this new design!

The PTCTNFMMFxxS-series coaxial arrester provides effective protection in an extremely compact form factor, and MMCX connectors for the lowest-profile connection.

PTCTNFMMFxxS OutlineAvailable with a TNC (f) bulkhead and MMCX (f) connectors, in a range of Protection Voltage/RF Power ratings.  See below and explore the datasheets to learn additional details!


Features:

  • DC to 6GHz Operating Band
  • Excellent Response and Residual Energy Reduction
  • Compact TNC to MMCX Bulkhead Protector
  • Low VSWR and Insertion Loss
  • Multi-strike, Rugged and Waterproof
  • Available in Multiple Protection Voltages: 90, 150, and 230V

Compact DC Block Arrestors For Radio Protection – Featured Product

We have added NexTek’s new coaxial arrestor product to the website and product selection tool, and you can now find information about all four variations!

The PTI series provides effective protection in an extremely compact form factor, and includes a series capacitor to block DC energy and further reduce the amount of energy that gets past and flows into the radio being protected.  This series capacitor guarantees effective protection from the Gas Discharge Tube front-end by eliminating the need to rely on or coordinate with the output-side capacitor of your radio.

NexTek’s SurgeGuard™ PTI series of DC-Blocked lightning arrestors operate at frequencies up to from 2Mhz to 2GHz.

Available with a TNC (f) bulkhead and SMA (f) connectors, in a range of RF pass band and RF Power ratings.  See below and explore the datasheets to learn additional details!


Features:

  • Excellent Response and Residual Energy Reduction
  • Compact TNC to SMA Bulkhead Protector
  • Low VSWR and Insertion Loss
  • Multi-strike, Rugged and Waterproof
