FIPLEX • Electromagnetic Devices for Radiocommunication Systems FIPLEX BIDIRECTIONAL AMPLIFIER - USER MANUAL Natural convection flow should be guaranteed trough heat dissipator in order to keep repeater temperature between safety margins (-30°C to +60°C). Keep minimum distance of 15 cm between heat dissipator and any object that could avoid free airflow circulation. Cold air Hot air Safety Any personnel involved in installation, operation or service of Fiplex repeaters must understand and obey the following: Repeaters are designed to receive and amplify signals from one or more base stations and retransmit the signals to one or more mobile stations, and vice versa. The repeaters must be used exclusively for these purposes and nothing else • Repeaters supplied from AC voltage must be connected to ground to guarantee safety operational conditions and to preserve the equipment. • Repeaters generate radio signals and thereby give rise to electromagnetic fields that could be hazardous to the health of any person who is extensively exposed to the signals at the immediate proximity of the repeater antennas. Coaxial cables insulation is made of polytetrafluoro ethylene, that could gives off small quantities of hydrogen fluoride when heated. Hydrogen fluoride is poisonous. Do not use heating tools when stripping coaxial cables insulation. 7 Document FIP-BDAM-07-EN
FIPLEX • Electromagnetic Devices for Radiocommunication Systems FIPLEX BIDIRECTIONAL AMPLIFIER - USER MANUAL AC Power THE POWER SUPPLY UNIT CONTAINS DANGEROUS VOLTAGE THAT CAN CAUSE ELECTRIC SHOCK. DISCONNECT THE MAINS PRIOR TO ANY WORK IN THE REPEATER. AUTHORIZED SERVICE PERSONNEL ONLY ARE ALLOWED TO SERVICE REPEATERS WHILE THE MAINS IS CONNECTED. Mains should be 110-220 VAC 50-60 Hz with ground terminal connection (yellow and green cable). A good ground connection must be done in order to preserve the equipment and system reliability. A 2 Amps fuse (5 x 20mm) is used as power supply protection against severe failure in mains power. DANGER ALWAYS REMOVE MAINS POWER BEFORE CHECKING OR CHANGING FUSES. 120 VAC CAN BE LETHAL. DC Power There is an alternative way to power the repeater, this is by means of a DC power source. DC power must be feed to the repeater main board by means of a specific connector (please see figure below). Accessing the repeater from the outside with the DC power cord must be done through the cable gland labeled “BATERY BACKUP”. Nominal DC voltage is specified in the repeater datasheet specifications. When DC voltage goes under the 80% of the nominal voltage, system will be in BATTERY FAIL status. 8 Document FIP-BDAM-07-EN
FIPLEX • Electromagnetic Devices for Radiocommunication Systems FIPLEX BIDIRECTIONAL AMPLIFIER - USER MANUAL Power connectors – Check polarity before connect In the presence of AC power, the system switchs automatically from DC power to AC power in order to preserve battery charge. Battery backup system is not provided with the repeater, nominal voltages and currents should be observed in order to prevent from malfunction. See specification sheet. For further assistance please contact factory. VERIFY THAT CABLE GLAND IS WELL FITTED IN ORDER TO PRESERVE WHEATER TIGHTNESS OF THE REAPETER. Static electricity means a potential source of permanent damage for essential parts of the repeater, if not handled carefully. NEVER TOUCH PRINTED CIRCUIT BOARDS OR UNINSULATED CONDUCTIVE SURFACES WITHOUT PROPER ELECTROSTATIC DISCHARGE PROTECTION. 9 Document FIP-BDAM-07-EN
FIPLEX • Electromagnetic Devices for Radiocommunication Systems FIPLEX BIDIRECTIONAL AMPLIFIER - USER MANUAL COMMISSIONING Repeater powers on when the mains is connected to the AC line, or if it’s available, when connected to a DC power source. No further field calibration or tune up of the repeater is needed to work properly. Repeaters are factory aligned and calibrated and are designed to retain calibration throughout the life of the product. Cover of the repeater must be always closed in order to preserve it from the environment and to assure reliability. When sited outdoors, repeater must not be opened in the following bad weather conditions such as: • Intense rainfall, snowfall or hail. • Storm or high wind. • Extremely low or high temperature. • High humidity of the air. Connection Connect the service antenna to the input/output N type female connector labeled “TO MOBILES”. Connect the donor antenna to the input/output N type female connector labeled “TO BASE”. Radiant system, antennas and coaxial cables to be used with the repeater must be adequate to work properly in the operation frequency bandwidth of the repeater. At least 18dB return loss value should be observed at the service and donor antennas connectors. Antenna Isolation ISOLATION BETWEEN DONOR AND SERVICE ANTENNAS MUST BE 20 dB HIGGER THAN THE MAXIMUM GAIN OF THE REPEATER. 10 Document FIP-BDAM-07-EN
FIPLEX • Electromagnetic Devices for Radiocommunication Systems FIPLEX BIDIRECTIONAL AMPLIFIER - USER MANUAL Isolation between Donnor and Service antenna If the isolation is less than the amplifier gain plus 20dB safety margin, then positive feedback sufficient for oscillation is present in the system. Such oscillations will overdrive one or both amplifier chains and continuously activate the AGC and overload circuitry, shutting down amplifiers in order to prevent them from damage. Poor isolation can cause permanent damage to the repeater and automatically voids warranty conditions. DO NOT POWER THE REPEATER IF “TO BASE” AND “TO MOBILE” CONNECTORS ARE NOT CONNECTED TO A RADIANT SYSTEM OR IF THEY ARE NOT TERMINATED WITH PROPER LOADS. Every time the repeater is powered on, it starts an automatic antenna isolation control procedure. This procedure takes around 30 seconds, during this time the repeater is not available for traffic, after the procedure is finished two things can occur: - Good isolation between antennas, in this case isolation control alarm will not be present and the repeater can be operated at maximum gain. - Poor or bad isolation between antennas, isolation control alarm will be present and the system will set repeater gain to a safe value, the repeater can not be operated at maximum gain. WHILE ISOLATION CONTROL IS PERFORMED THE PRESENCE OF UPLINK SIGNALS SHOULD BE MINIMIZED. AVOID DE USE OF MOBILE DEVICES NEARBY THE REPEATER DURING ISOLATION CHECK. 11 Document FIP-BDAM-07-EN
FIPLEX • Electromagnetic Devices for Radiocommunication Systems FIPLEX BIDIRECTIONAL AMPLIFIER - USER MANUAL DOWNLINK GAIN SETUP Manual Gain Setup Downlink gain control is achieved setting up the desired attenuation value by means of tact switches, value of attenuation is displayed in two seven segments displays located at the right of the attenuation controls (please see figure below). Attenuation values runs from 0dB (nominal gain condition), up to 25dB (maximum attenuation or minimum gain), in steps of 1dB. If isolation level between antennas is not enough, repeater automatically sets the maximum gain value allowed in order to prevent unwanted oscillations. Under this circumstances user will not be able to set attenuation values that may take the repeater to a non secure operating condition (usually nominal gain is never achieved). Downlink gain manual control 12 Document FIP-BDAM-07-EN
FIPLEX • Electromagnetic Devices for Radiocommunication Systems FIPLEX BIDIRECTIONAL AMPLIFIER - USER MANUAL If “AGC ON” led indicator is on when the repeater starts operating, this means that signal received from the donor site is above minimum signal level required for nominal gain operation so AGC circuitry is active. Under this condition of operation user should attenuate the gain level of the repeater using DOWN control, decreasing gain until “AGC ON DOWNLINK” indicator turns off. This operation is recommended in order to release dynamic range to the AGC circuitry. Automatic Gain Control (AGC) Automatic Gain Control circuitry is intended to keep repeater’s output power at a fixed level when input signals exceed maximum values, avoiding quality signal degradation by intermodulation generation. If “AGC ON Downlink” led is on this means that signal level from donnor site plus repeater gain produces an output power that is above the maximum composite output power of the repeater. This should not be considered an undesired working condition, far from that; this is the best operating condition because you are getting the maximum composite output power available from the repeater. Anyway is a good practice (if manual attenuator is set to a value different from zero), to increase attenuation (reducing gain), until AGC led turns off, this operation releases AGC circuitry dynamic range. Also is a good practice to check signals from donor site to ensure that undesired signals are not being amplified by the repeater, or even desired signal levels are not excessively high taking repeater to an overload condition. Overload Protection When the automatic gain control circuit reaches its limit (20 dB), the power amplifier stage is shut down to prevent harmful distortion and potential damage to the repeater. After approximately ten seconds the system checks if overload condition is still present, if this happens amplifiers will remain off. This cyclic check will continue until condition that makes AGC circuitry reach its limits desapears. Conditions that can cause AGC to reach its limits include the presence of one or more very strong channels, a strong in-band noise source, or amplifier oscillation due to poor antenna isolation. When overload protection is active led labeled “OVERLOAD DOWNLINK” is on. 13 Document FIP-BDAM-07-EN

Attenuation values runs from 0dB (nominal gain condition), up to 25dB (maximum attenuation or minimum gain), in steps of 1dB.

FIPLEX • Electromagnetic Devices for Radiocommunication Systems FIPLEX BIDIRECTIONAL AMPLIFIER - USER MANUAL Automatic Gain Control (AGC) Automatic Gain Control circuitry is intended to keep repeater’s output power at a fixed level when input signals exceed maximum values, avoiding quality signal degradation by intermodulation generation. Signals received from mobiles have a different nature that the ones received from donor site or BTS, so it is rare that “AGC ON Uplink” led keeps on, if this occur, repeater gain should be decreased. Is a good practice to set identical gain values in both (uplink and downlink) paths to keep a good link budget balance, so is very recommended to take downlink manual gain value as a reference for the uplink path. This balanced operation mode prevents BTS desensitation or saturation from uplink signals amplified by the repeater. Overload Protection When the automatic gain control circuit reaches its limit (20 dB), the power amplifier stage is shut down to prevent harmful distortion and potential damage to the repeater. After approximately ten seconds the system checks if overload condition is still present, if this happens amplifiers will remain off. This cyclic check will continue until condition that makes AGC circuitry reach its limit desapears. Conditions that can cause AGC to reach its limit include the presence of one or more very strong channels, a strong in-band noise source, or amplifier oscillation due to poor antenna isolation. When overload protection is active led labeled “OVERLOAD UPNLINK” is on. 15 Document FIP-BDAM-07-EN
