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.

lightning protection. M/A-COM is an ISO-9001 globally

Description
l/4 stub tuners are three port coaxial devices which employ a
short circuit element as a means of protection against lightning
or EMP strikes. 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.
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.
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.
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.

Excellent for Broadband Frequency Applications
Field Replaceable Gas Discharge Tube
Available Interfaces Facilitate Retrofit Capabilities
Low VSWR up to 2.5GHz
Specialized White Bronze™ Finish
Description
Surge protectors incorporate hermetically sealed gas discharge tube (GDT) technology within the coaxial transmission
line to provide a low impedance path to discharge the EMP to
ground. 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.

Application Notes
Recommended
Mounting Techniques
To ensure that proper, low level contact resistance is established between the LP device
and mounting wall, it is recommended that a minimum torque of 50 in/lbs / 5.65 n/m
be applied to tighten the connector mounting nut. 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.
