ID 2011 V4.00 RF Coaxial Lightning & EMP Protection • In-line RF Coaxial Protection Against Lightning & EMP • Ideal Protection for Cellular Infrastructure Equipment • Available in l/4 Stub Tuner or Gas Discharge Tube Formats • Maintains Protection after Initial Strike or Pulse M/A-COM offers a complete series of RF Coaxial Lightning & EMP Protection Devices for use in cellular infrastructure applications. EMP (electro-magnetic pulse) occurs primarily as a result of direct lightning strikes to infrastructure equipment which can produce fast rising electric fields within micro seconds. These electric fields induce high voltage pulses through unprotected antennas and coaxial transmission cables which can ultimately lead directly to the primary communication equipment. The EMP threat, generated from unpredictable lightning strikes is a serious concern for cellular operators around the world. Damage from a lightning strike can result in costly repair of equipment as well as significant loss of airtime service to subscribers. M/A-COM RF coaxial lightning protection (LP) devices have been designed for use in commonly deployed cellular infrastructure including GSM, NAMPS, PCS 1900 and DCS 1800 operating formats. The use of coaxial lightning protection has two primary benefits for cellular applications. First, RF coaxial lightning protection can easily be inserted into existing infrastructure architecture either as a cable assembly or as an in-line adapter. This facilitates cell site design and retrofit capabilities. Secondly, the RF coaxial protection has been designed to facilitate and not degrade RF performance during normal operation of the system. Surge Protectors These devices incorporate internal gas discharge tube (GDT) technology to provide a low impedance path to discharge the EMP to ground. The GDT is hermetically sealed with an inert gas which is not radioactive and requires no special handling. GDT devices are broadband due to their inherently small capacitance and cover frequencies up to 2.5 GHz. Once a GDT device has been activated with an impulse and the voltage level dissipated, the device becomes inactive and will require subsequent maintenance or replacement. Surge protectors are available in convenient bulkhead mounting configurations with a wide variety of standard interface choices including Type N, 7-16 and SMA. l/4 Stub Tuners l/4 stub tuners are three port coaxial devices. The third port, extending from the main electrical path, serves as a terminated short circuit element at a predetermined distance from the RF transmission path. This distance is designed to be exactly one quarter wavelength at the desired centering frequency (Fo). l/4 stub tuners offer very low VSWR and feature very high attenuation of incoming pulses but must be applied across relatively narrow bandwidths (± 70 MHz). M/A-COM offers standard designs for the most popular cellular frequency bands to facilitate usage without the need for a custom design. Stub tuners offer the greatest protection for sensitive electronic components as they have neither the sparkover or residual voltage characteristics of GDT devices. Stub tuners are extremely reliable and maintenance free since they incorporate no active components. Standard stub tuner designs exist for GSM, PCS 1900 and DCS 1800 frequencies with a wide variety of connector interfaces such as Type N and 7-16 available. Cable assemblies, including low loss cable options, are also available to provide complete in-line solutions for base station design.

The third port, extending from the side of the main transmission path of the connector, is terminated in a short circuit at a predetermined distance from the main path. The distance is calculated to be exactly one quarter wavelength (l/4) at the desired centering frequency (Fo). In order to offer the most flexible solutions for infrastructure applications, stub tuners are available in either an individual connector format or as a cable assembly ready for direct installation into a RF coaxial transmission line. A wide variety of interface styles are available to meet existing retrofit or new design requirements including Type N, and 7-16. Standard crimp tooling is available to facilitate direct connector termination to RG58 or low loss Times™ T-Flex 402 cables. Stub tuners, by the nature of their short circuit designs, do not have a sparkover or residual voltage as found in surge protectors. This ensures the greatest levels of protection against repeated lightning or EMP strikes within specified frequency bands. Stub tuners are also extremely reliable and maintenance free since they contain no active parts. This characteristic can be important when considering the total cost of ownership, including the need for replacement or repair of the device within difficult to reach infrastructure equipment. Application Information The centering frequency is an important selection criteria because l/4 stub tuner design techniques restrict the bandwidth in which acceptable VSWR performance can be achieved. Stub tuners exhibit a v-shaped VSWR response. Typically this bandwidth is 8% of the centering frequency. Specified bandwidth in excess of 8% begins to experience degradation of VSWR at the centering frequency. Stub tuners are frequency specific in application as opposed to surge protectors which address a wider spectrum of frequencies. As a result of this restriction, M/A-COM offers a wide range of standard stub tuner devices which address commonly deployed cellular frequency bands such as GSM, NAMPS, PCS 1900 and DCS 1800. Some alternative plating finishes are available with M/A-COM’s Stub Tuner Lightning products. Standard plating finishes are shown within the data sheet, but alternatives are available by customer request. Details of M/A-COM’s new “White Bronze” finish are shown in the application notes associated with this data sheet. For more detailed information, please contact your local M/A-COM field sales office.

The GDT is loaded into the connector housing from the side via a weather sealed access port. The GDT does not require special handling or safety precautions as the inert gas used is non-radioactive. In an active state, the transversemounted GDT introduces some inherent extra capacitance which is compensated electrically in the design and does not degrade overall VSWR performance. As a result, M/A-COM surge protectors perform well in applications up to 2.5 GHz. Surge protectors are made active when a high voltage impulse generated from a lightning or EMP source appears on the coaxial line. The electric field produced causes the inert gas to ionize which then creates a very low impedance path to ground, thus directing the current away from sensitive electronic elements. Once the impulse ceases and the voltage level reduces, the GDT becomes inactive again leaving a residual voltage on the coaxial line. M/A-COM supplies devices with a selection of GDT elements to carry 10kA, 20kA or 50kA peak current. In addition, GDT devices are available with a wide variety of interfaces such as type N, 7-16 and SMA to facilitate retrofit installation. Application Information The significant advantage of using surge protectors is their ability to handle a wide bandwidth from DC to 2.5 GHz. Applications where multiple frequency bands need to be transmitted at the same time also benefit from the surge protector design characteristics, i.e. the device is required to pass DC or low frequency AC bias voltages as well as primary transmit or receive signals, but in addition required to stop high voltage impulses. In operation, the gas discharge tube continues to exhibit a voltage drop of about 20 volts while the device remains in an energized state. It is important to note that there will be a small period prior to the device becoming active when high energy will be present on the transmission line. This is because the ionization of the inert gas is inherently not instantaneous. The time taken for the GDT to become fully active is determined by the rise time of the applied impulse, typically in the order of 1kV/µS, and the impulse sparkover voltage which is normally 800 volts. Standard devices will therefore take 800nS typically to reach full condition. High energy for this period of time may not be acceptable in some applications and should be considered as a system design parameter. GDT techniques employed for lightning or EMP protection have a finite life span once activated. When measured, this is found to be inversely proportional to the level of energy dissipated by the device. In tests, the GDT devices will withstand multiple impulses of 20kA but only a single impulse of 50kA. It is important to note that once failure occurs, the device remains a short circuit to guarantee continued protection. To facilitate the maintenance and reduce the expense of GDT based systems, M/A-COM has designed these devices to be field replaceable. Replacement GDT capsules are available for field installation after a subsequent lightning or EMP strike. Surge protectors have been specifically designed with fullyretained sealed covers which are located in an accessible location to facilitate maintenance. GDT capsules require only a standard wrench for field replacement. Surge protectors are plated standard with M/A-COM’s specialized White Bronze™ finish, specially formulated to provide corrosion resistance in potentially aggressive physical environments. White Bronze™ plating is ideal for wireless applications due to its excellent conductivity, and non-ferrous composition for low intermodulation characteristics. Detailed application notes are available for proper selection of lightning protection devices (surge protectors & stub tuners) as well as intermodulation and White Bronze™ plating. Please refer to the application section at the back of this data sheet for more details on availability of these application notes. Specifications Subject to Change Without Notice.

A recommended minimum torque of 35 in/lbs / 3.95 n/m should also be applied for installation of replacement surge protector capsules to ensure proper protection performance. Surge Protector Mounting Techniques In order to ensure that resultant currents from lightning or EMP strikes do not interfere with parallel transmission lines within protected electronic equipment, surge protector devices must be installed with proper orientation. The surge protector side of the device should be mounted in the unprotected side of the equipment while the mounting nut is positioned internally in the protected area. Lightning Protection Planning It is important when planning lightning protection, that the user can estimate the potential number of direct strikes. This information may influence the type of device selected or the requirement for routine maintenance checks. Significant attention must be paid to the height of supporting structure as this, when related to the typical number of thunderstorms in a particular region, allows us to estimate the probability of a direct strike taking place. To assist our customers in this, the following table and chart has been included in this note. This should enable lightning protection planners to establish the likelihood of direct strikes across a network anywhere in the world.
