White Papers

Determining where to attach a ground wire to an RF coaxial surge arrestor without a ground screw is just one of the many steps required to properly ground the surge arrestor.

Citizens Broadband Radio Service (CBRS) networks have emerged with a single platform that meets the diverse needs of countless organizations. It offers a spectrum that can be used exclusively by an organization as well as more coverage, capacity, security, and control. The first part of this white paper details the traits and main benefits of a CBRS network. The second part explains the importance of protecting a CBRS network from destructive power transients caused by lightning strikes and other sources.

In this paper we discuss the main causes and effects of PIM distortion as well as the qualities, benefits, and applications of 2.2-5 low-PIM RF connectors. We also cover a closely related topic − the surge protection needs of wireless networks, and we conclude with information about a PolyPhaser product that meets these needs: our quarter-wave stub SPD with 2.2-5 low-PIM RF connectors.

The Infinite Electronics international DC block (PolyPhaser IS-B50 / IS-50) and other GDT based surge arrestors can be field tested to qualify whether they are working or not working.

The latest NEC 2020 Sections detail the requirement of surge protection devices (SPDs) in specific applications. In this document, we will go through each section and identify the application, provide examples, and identify potential surge protection solutions.

A simple, effective surge protection device (SPD) ensures continued service, minimizing costly site repairs and lost revenue. If the SPD is not engineered to the correct specifications using appropriate technology, it may initially protect network devices. However, the SPD may compromise the integrity of data signals, causing intermittent communication issues.

Small footprint and increased PIM performance, many cellular radio users are standardizing on coaxial 4.3-10 connectors, especially in compact applications such as small cells. While 4.3-1...

This paper discusses the possibility, requirements and necessary steps to protect land mobile vehicles from the effects of an electromagnetic pulse event to ensure continuous mobility of the vehicle.

The incidence of damage to equipment in general is higher from power line surges than by any other I/O port. This is not to say more energy comes through the power line, just that the damage is more v...

Antenna manufacturers utilize shunt-fed dc grounded antennas as a means of impedance matching and providing some form of lightning protection to their customers. It has been proven that these antennas...
