1. SAFETY CONSIDERATIONS
1.1 Electric Shock Hazard
Electrical shocks due to faulty mains driven power supplies.
Whilst ever potentially present in any electrical equipment, such a condition would be
minimised by quality installation practice and thorough testing at:
a) Original assembly
b) Commissioning
c) Regular intervals, thereafter.
All test equipment to be in good working order prior to its use. High current power supplies
can be dangerous because of the possibility of substantial arcing. Always switch off during
disconnection and reconnection.
1.2 RF Radiation Hazard
RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to
AFL’s equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or because a ‘spare’
output has been left unterminated. Either of these conditions would impair the system’s
efficiency. No investigation should be carried out until all RF power sources have been
removed. This would always be a wise precaution, despite the severe mismatch between the
impedance of an N type connector at 50Ω, and that of free space at 377Ω, which would
severely mitigate against the efficient radiation of RF power. Radio frequency burns could
also be a hazard, if any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both local & statutory)
regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is
capable of producing RF field strengths, which may exceed guideline safe values especially if
used with antennas having appreciable gain. In this regard the use of directional antennas
with backscreens and a strict site rule that personnel must remain behind the screen while the
RF power is on, is strongly recommended.
IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, a
separation distance of at least 20cm must be maintained between the leaky feeder attached to
this device and all persons. Furthermore the gain of antennas attached must be chosen and
located so as to satisfy the MPE categorical exclusion and co-location requirements.
Where the equipment is used near power lines, or in association with temporary masts not
having lightning protection, the use of a safety earth connected to the case-earthing bolt is
strongly advised.

1.3 Chemical Hazard
Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes used
in devices within equipment produced by Aerial Facilities Ltd. Beryllium oxide dust can be
toxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by
contact.
Products that contain beryllium are load terminations (dummy loads) and some power
amplifiers. These products can be identified by a yellow and black “skull and crossbones”
danger symbol (shown above). They are marked as hazardous in line with international
regulations, but pose no threat under normal circumstances. Only if a component containing
beryllium oxide has suffered catastrophic failure, or exploded, will there be any danger of the
formation of dust. Any dust that has been created will be contained within the equipment
module as long as the module remains sealed. For this reason, any module carrying the
yellow and black danger sign should not be opened. If the equipment is suspected of failure,
or is at the end of its life-cycle, it must be returned to Aerial Facilities Ltd for disposal.
To return such equipment, please contact the Quality Department, who will give you a
Returned Materials Authorisation (RMA) number. Please quote this number on the packing
documents, and on all correspondence relating to the shipment.
PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite Materials
Many modules/components in AFL equipment contain P.T.F.E. as part of the RF insulation
barrier.
This material should never be heated to the point where smoke or fumes are evolved. Any
person feeling drowsy after coming into contact with P.T.F.E. especially dust or fumes
should seek medical attention.
1.4 Emergency Contact Numbers
The AFL Quality Department can be contacted on:
Telephone +44 (0)1494 777000
Fax +44 (0)1494 777002

2. OVERVIEW/SYSTEM DESCRIPTION
The equipment covered in this manual is a UHF Bi-directional Amplifier (also known as a
Repeater). Its main sphere of application is in urban areas where the topography is such that
shadows occur in the propagation pattern (for example within large buildings, conference
centres and tunnels, etc.)
The Amplifier is a 4-port device for direct connection to two Base facing antennas, usually a
highly directional Yagi or similar aligned towards the base (donor) site, and two radiating
cable feeders to cover the mobiles. The channel frequencies passed by the Amplifier are set
as per the specific customer requirements. In this instance, the channel module frequencies
have been ‘hard-wired’ and so it is not possible to change frequencies without some reconfiguration of the channel programming.
The system for which the Amplifier is to be used with is mainly duplex channel UHF radio
system but with a single simplex channel. The duplex channels operate constantly in each
direction using the Base Antenna port 2 and Radiating Cable port 2. There are five
Downlink (Base Transmit) duplex channels and four Uplink (Base Receive) duplex
channels. In addition there is the Uplink simplex (talkaround) channel operating via these
ports.
The Downlink simplex channel operates through the Base Antenna port 1 and Radiating
Cable port 1 ports. This is to avoid any interaction between the common frequency channel
high gain paths. Using separate antennas adds the isolation required for the simplex part of
the Amplifier to work.
The simplex channels are not constantly operating in their entirety. Instead, each simplex
path has the output amplification disabled and when an input is detected in one path that
amplifier will be switched on and the other path will be held off until that input signal has
stopped. In this way, the simplex part of the system is constantly ready to pass the channel in
either path.
The Bi-directional Amplifier consists of six different 19” rack mount 4U chassis. These are
a Base side Duplex/PA chassis (AFL part: 50-063702) to provide the link with Antenna 2
and the remainder of the system. In addition there is a Tunnel side Duplex/PA chassis (AFL
part: 50-063705) to connect the Radiating cable 2 to the remainder of the system. The
channel selectivity is made in the Downlink by a Downlink Channel chassis (AFL part: 50-
063703) and in the Uplink by the Uplink Channel chassis (AFL part: 50-063704). The
Downlink simplex channel and part of the Uplink simplex channel circuit is housed in the
Simplex chassis (AFL part: 50-063706) and there is a Power Supply chassis (AFL part: 50-
063707) to provide the DC supply to each of the five RF units.
The Bi-directional Amplifier is housed in a single 38U 19” rack. All external connections
are made towards the bottom of the rear of the rack suitable for cable entry via cable ducts
through the open underside of the rack. External connections are for the 110V AC input,
four ‘N’ type female RF connectors and a Krone block for the alarm output.

For better understanding of the system, the system diagram on page 23 should be consulted.
Downlink path
Duplex system signals in the Downlink path arriving at Base Antenna port 2 are first passed
to the Base side chassis and so through a duplexed bandpass filter to ensure good input
selectivity. This is then followed by a 31dB gain LNA to provide some amplification and a
switchable attenuator then allows up to 30dB of gain adjustment in 2dB steps.
From here signals are routed to the Downlink Channel chassis where a 2 way splitter is
followed by two three way splitters to provide six equal paths. One of these is terminated
with a 50ohm load and the remaining five each connect to a channel selectivity module. The
Downlink channel modules offer 15dB gain and have ALC circuitry to limit the module
output to -25dBm. This is ensure that the total output power may not become higher than the
specified level. The channel module outputs are taken to two three way combiners for
connection to a two way combiner which then routes signals out of the Downlink Channel
chassis and to the Tunnel side chassis.
The Downlink duplex channel frequencies factory set are:
457.050MHz
458.225MHz
457.850MHz
457.300MHz
457.775MHz
In the Tunnel side chassis a 21dB gain LNA is then followed by a 15dB gain LPA to drive a
23dB gain 20Watt Power Amplifier which provides the final stage of amplification. The
Power Amplifier is followed by a duplexed bandpass filter connecting to the Radiating cable
port 2.
The Downlink simplex channel, 452.850MHz, is received at Base Antenna port 1 and is
passed through a bandpass filter to provide selectivity. A 31dB gain LNA then provides
initial amplification and this is followed by a switchable attenuator giving up to 30dB of
gain adjustment in 2dB steps. An ALC attenuator is then fitted for muting the input of the
channel module when an Uplink path signal has been detected and is being amplified in that
direction. The channel module following the attenuator has 15dB of gain and has ALC
circuitry to limit the module output to -20dBm to limit the total output power to that
specified in case of an increase in off-air signal input. The channel module is followed by a
31dB gain LNA and then a 15dB gain 1Watt LPA. A bandpass filter after the LPA connects
to the Radiating cable port 1.
Uplink path
All Uplink channels enter the Bi-Directional Amplifier at Radiating Cable port 2 and pass to
the Tunnel side chassis where a duplexed bandpass filter routes the signals to the Uplink
input amplifier, a 31dB gain LNA. A switchable attenuator then gives up to 30dB of gain
adjustment in 2dB steps before signals connect to the Uplink Channel chassis.
In the Uplink Channel chassis, a 2 way splitter connects to two three way splitters to provide
six equal paths. One of these is unused and so is terminated with a 50ohm load. Four of the
remaining paths each connect to a channel selectivity module giving 15dB gain with an
ALC limited maximum output of -23dBm. The four module outputs then connect to a four
way combiner for routing to the Base side chassis. The last of the six paths is routed to the
Simplex chassis which will be described later in this section.

The Uplink duplex channel frequencies are factory set:
452.050MHz
453.225MHz
452.300MHz
452.775MHz
The four Uplink duplex channels arrive in the Base side chassis and pass through a 21dB
gain then a 15dB gain LPA driver before a 23dB gain 20Watt Power Amplifier. There is an
isolator fitted at the PA output to provide protection from the Uplink simplex channel path.
A 2 way combiner then combines the four duplex channels with the simplex channel and a
bandpass filter then connects to the Base Antenna port 2.
In the Simplex chassis, the Uplink path from the Uplink Channel chassis is first routed
through two ALC attenuators to mute the input to the Uplink channel selectivity module
when a Downlink simplex signal is being passed in the other path. A channel selectivity
module, set for 452.850MHz, then gives 25dB of gain and has an ALC level of -17dBm.
The module is followed by a 31dB gain LNA and then a 15dB gain LPA with an isolator at
the output to provide protection from the duplex path PA. The Uplink simplex signal then
connects to the Mobile side chassis for routing to the 2 way combiner.
The Power Supply Unit operates from an AC supply of 110V and has a 7.5Ampere circuit
breaker to switch the chassis On or Off. A 15A filter then provides some protection against
instabilities in the AC supply. There are two 400Watt PSU modules fitted and the outputs of
these are distributed to six 24V DC output sockets at the rear of the Power Supply chassis.
The RF connectors used for user interface are ‘N’ type female and interconnecting RF
chassis connectors are SMA female. Each of the five RF chassis has a DC input fuse and the
front panels have a green ‘Power ON’ LED and a red ‘ Alarm’ LED. The Power Supply
chassis has a single green ‘Power ON’ front panel LED.
Each chassis has a summary alarm output connecting to the Krone block at the lower rear of
the rack for user interface. In addition, the 19” rack has intruder alarms fitted to the front and
rear doors of the rack. The alarm outputs may be connected to singly or in parallel as a rack
summary. The alarm outputs are voltage free dry contacts being Closed in normal operation
and Open in an Alarm state.
