MR Booster Manual (MN001808-1, 9/99)Page 3Section 2. System Description2.1 IntroductionThis section describes the basic functions and features of an MR Booster, including:• System overview• Theory of operation• System components2.2 System OverviewThe MR Booster is a broadband, bi-directional amplifier (BDA) used to extend thecoverage area in a wireless communications network. The booster is specificallydesigned to interface with the MIKOM MR series repeater. It can also be used withan existing repeater or a base transceiver station (BTS) that needs a downlink powerboost.Figure 2-1 illustrates a typical MR Booster application with a repeater, and Figure 2-2 illustrates a typical application with a BTS. The booster is connected directly to thecoverage antenna port from the repeater or BTS and boosts the downlink signalpower while maintaining dynamic range on the uplink. The booster performs severalbasic functions to enhance network coverage:• The repeater or BTS downlink RF output is filtered, amplified and transmitted,via the mobile coverage antenna, using high efficiency RF power amplifiers.• Uplink RF signals from handsets in the coverage area are received at the mobileantenna, amplified by an LNA, and passed directly to the repeater or BTS.• Control and alarm monitoring is maintained by MR repeater software or throughtwo relay contact outputs from the booster.• Power supply and power amplifier soft-fail redundancies offer increasedreliability.• A separate uplink diversity path is available as an option.• Downlink output VSWR monitoring is available as an option.

MR Booster functional block diagram2.3 Theory of OperationA block diagram of the basic high-power MR Booster system is shown in Figure 2-3.In order to simplify the discussion, a repeater-booster installation is assumed as inFigure 2-1.2.3.1 Downlink pathDuplexed RF from the repeater’s coverage antenna port is connected to thebooster repeater port. The repeater duplexer then routes the downlink signalfrequencies to the PA combiner/splitter module.POWERSUPPLYAPOWERSUPPLYB+12V+26V-A +26V-B+12V+12V+26V-A+26V-BLOGICCONTROLLER+12VI2CCONTROL I/ORepeater or BTSmain portRepeater or BTS diversity port+26VMAIN LNADIVERSITY LNAPOWER AMPLIFIERSRPTRDUPLEXERMOBILEDUPLEXERUL FILTERPACOMBINER/SPLITTER PACOMBINER/SPLITTERMain coverageantennaDiversity coverageantenna
2. System DescriptionPage 6MR Booster Manual (MN001808-1, 9/99)In the high-power option, the RF is split into four separate paths by the hybridcombiner/splitter module and distributed to four RF PAs. In the medium-power option, the RF is split into two separate paths and distributed to two RFPAs.NOTE: The multiple amplifiers provide soft-fail redundancy to maintainminimum output power capability should one or more fail in the field.The PA outputs are summed in a second combiner/splitter, then routed to themobile-side duplexer. The duplexer routes the downlink RF output to thecoverage antenna, which transmits to handsets in the booster coverage area.2.3.2 Uplink pathMobile handset transmissions are received at the mobile duplexer port androuted to the LNA input by the mobile duplexer. The amplified LNA outputis then routed to the repeater duplexer, which is connected to the installedrepeater’s coverage antenna port.A diversity option offers a second, identical uplink path when diversity is inuse in the donor BTS or repeater.2.3.3 System controlControl functions include PA keying, fan control, and uplink attenuationsetting. Monitored parameters include PA output power, status, systemtemperature, power supply temperature, DC output voltage and status, andinput power source (ac or dc).Resident software can be accessed via the supplied serial interface cable witha laptop computer and terminal-emulation software to initialize and customizethe unit during installation or to perform troubleshooting.The booster can be remotely controlled after installation with a Mikom MRseries repeater via the I2C bus interface cable.For other applications, or if remote control is not required, a pair of relayclosure outputs from the booster can be user-configured and routed to thedonor system to flag system problems after installation.

2. System DescriptionMR Booster Manual (MN001808-1, 9/99)Page 92.4 System Components2.4.1 Power SupplyThe MR Booster provides two high-efficiency power supplies with 26 VDCand 12 VDC outputs (see Figures 2-4 and 2-5). The 26 V output is splitevenly between the system PAs to provide soft-fail redundancy. The 12 Voutput is diode-connected at the controller and the LNAs, ensuring that bothwill function if a power supply fails. The power supply has thermalshutdown capability.The AC supply input is auto-ranging to handle 115 and 220 volt, 50 or 60 Hzsystems. During loss of AC mains, the booster will automatically switch overto the DC input for operation with a BBU.2.4.2 Downlink Power AmplifierThe downlink power amplifiers (see Figure 2-4) provide low distortionamplification of downlink RF signals using proprietary feedforwardcorrection techniques. After duplexer, splitter and combiner losses, the PAsprovide 20 dB nominal gain for the booster in the downlink signal path.The amplifiers are powered by the 26 VDC output of the power supplies. Toprovide maximum output power and soft-fail redundancy, the downlink power isshared between either four (high-power option) or two (medium-power option)PAs. Each PA provides output power and temperature status information to thesystem controller and provides both overcurrent and overtemperature protectioncircuitry.2.4.3 Logic Controller BoardThe logic controller board (see Figure 2-4) monitors and controls internalbooster functions, and provides alarms to the donor system. The controllercontains an I2C bus interface for remote control by a Mikom MR seriesrepeater. The controller is powered by the 12 VDC supply.System configuration information is retained in an on-board EEPROM. Forinstallation or troubleshooting, the board-resident software can be accessedfrom an MR repeater, or from an on-site laptop computer. The controller canset:• uplink gain• PA key/unkey• fan speed control (high/low/off)
2. System DescriptionPage 10 MR Booster Manual (MN001808-1, 9/99)The controller monitors the status of the following system components:• PA power output• PA temperature• PA shutdown• power supply temperature• average 26 VDC and 12 VDC output voltages• AC mains presence• DC output VSWR (when installed)The controller also routes the DC power to the VSWR module.For general use, two alarm outputs are provided that can be user-configuredduring installation. The outputs are normally open relay contact pairs, whichare closed when no alarm condition is present. These signals are provided onfour of the seven pins of a terminal block on the controller board.2.4.4 PA Combiner/Splitter ModuleThe PA combiner/splitter module (see Figure 2-4) splits the input signal,distributes it to the PAs and combines it after amplification. Identical hybriddesign is used to ensure maximum amplitude and phase matching of thedownlink signal.2.4.5 Uplink Low Noise AmplifierThe LNA (see Figure 2-4) maintains dynamic range for uplink mobilesignals. The LNA provides low noise figure and high input IP3 so the boosterdoes not decrease sensitivity or increase distortion in the system.The gain of the LNA chain after duplexer and cable losses is nominally 20 dBwith the uplink attenuation set to 0 dB. Using the internal software, the gaincan be reduced by increasing the attenuation in 1 dB steps up to 15 foroptimal IP3, or where equal uplink and downlink booster gain is notnecessary. The same LNA is used in the diversity option and the attenuationsetting is ganged so each uplink path is set for equal gain.
2. System DescriptionMR Booster Manual (MN001808-1, 9/99)Page 112.4.6 DuplexersThe duplexers (see Figure 2-4) provide isolation between uplink anddownlink paths, and band-limit the signals that are either passed to the donorhardware, or transmitted at the mobile antenna. The small repeater duplexerprovides adequate UL/DL isolation. The mobile duplexer offers low insertionloss to maximize downlink output power and uplink noise figure. Forwardand reverse directional coupler outputs are provided on the mobile duplexer.The coupler outputs are routed to the VSWR module when that option isinstalled.2.4.7 RF CablesThe RF cables are a critical part of the MR Booster, particularly in thedownlink function. Low loss provides maximum output power and cablepropagation delays must be properly controlled so that the amplifiers arecombined with low phase error.2.4.8 Fan Assembly (High-power only)Dual DC fans (not shown) maintain a low cabinet temperature in the highpower option. The fans are sealed to withstand all weather conditions. Theplenum and ducting structure of the booster is designed to move air over allheat fins, even if one fan fails. The fans can be disabled or operated at lowspeed for climates where over-heating will not be a problem. The logiccontroller provides the fan interface.2.4.9 VSWR Module (Optional)The VSWR module (not shown) monitors the downlink output VSWR. Thecustomer is alerted to potentially damaging antenna mismatch. The modulereceives ± 12 VDC from the controller and coupled outputs from the mobile sideduplexer. The coupled signals are processed and an analog voltagerepresentative of the output VSWR is routed to the logic controller.CAUTION: Never substitute RF cables in the booster. Use onlyproper MIKOM part numbers.
2. System DescriptionPage 12 MR Booster Manual (MN001808-1, 9/99)2.4.10 Downlink Driver Amplifier (Optional)An ultra-linear driver amplifier (not shown) provides more downlink gain orincreased drive for the MR Booster PAs.

Typical MR Booster application (repeater)3.5 System OptimizationRefer to Figure 3-5 for an example of an application in which the MR Booster is usedto boost a repeater. For additional information regarding system optimization, pleasecontact Mikom technical support at 1 (800) 800-7465.3.5.1 Downlink Gain SettingThe downlink gain is generally determined by the output power that providescoverage of the hole that the MR Booster is filling. This power should notexceed the specifications in Section 6 for differing technologies and numberof carriers. The gain of the repeater must be adjusted via the operationalsoftware so that the desired output power equals the system gain (repeaterplus booster) plus the input power received from the BTS.The input power can be determined from the downlink RSSI reading of therepeater for each applicable RF channel. For greatest accuracy, the factorytest data sheet enclosed with the MR Booster can be used to determine thebooster gain near each channel of interest.3.5.2 Downlink Power MeasurementTo ensure that the proper output power is reached, measure the compositepower coming out of the mobile duplexer port. Use a power meter capable ofhandling 100 mW with a 30 dB, 60 W power attenuator on the mobileconnector for an accurate measurement without damage. The compositepower measured by the meter, after calibrating out the loss of the attenuator,should be approximately equal to the desired power per carrier plus 10logN,where N is the number of carriers.
3. InstallationPage 26 MR Booster Manual (MN001808-1, 9/99)3.5.3 Uplink Gain SettingIn most cases, the repeater gain is adjusted to make the uplink gain equal tothe downlink gain to maintain a balanced link. Adjust the repeater gain, leavethe MR Booster LNA gain set to maximum, and the overall system noisefigure is minimized.In cases where unusually strong in-band interferers are present, it may benecessary to decrease the LNA gain in order to increase the overall systeminput intercept point. The amount of attenuation added depends on therequired system intercept point, the maximum allowable system noise figure,and the dynamic range of the repeater.

Counts maybe zeroed by entering ALA=0.• Alarm log rate: Some alarms are checked as often as five times a second.To prevent a single alarm condition from running up the count, a givenalarm is logged, at most, one time in 10 minutes. The alarm counts maybe interpreted as the number of 10-minute intervals in which the alarmoccurred.There is one exception: the PA Out of Service alarm, which is really not alog, but reflects the current condition of the PA.>ALAPOWER AMPLIFIER FAULTS RECORDED...PA: 1 2 3 4PA OUT OF SERVICE ALARM 0 0 0 0PA TEMP HIGH ALARM 2 2 2 2PA POWER HIGH ALARM 2 2 2 2PA POWER TOO LO ALARM 0 0 0 0PA OVER CURRENT ALARM 0 0 0 0POWER SUPPLY FAULTS RECORDED...POWER SUPPLY: 1 2POWER SUPPLY TEMP ALARM 1 1AC POWER LOST ALARM 0 0DC VOLTAGE ALARM 1 1press any key to continue...SYSTEM FAULTS RECORDED...ROM ALARM ..................... 0EEPROM ALARM .................. 0VSWR HIGH ALARM ............... 0CABINET DOOR OPEN ALARM ....... 0GEN PURPOSE ANALOG INPUT ALARM 0GEN PURPOSE DIGITAL INPUT ALARM 0
A. Software ControlMR Booster Manual: Appendices (MN001808-1, 9/99)Page A-19• Automatic Restore to Service: If an alarm condition causes a PA to betaken out of service, the system will continue to process calls using PAs.Periodically, the controller will attempt to restore out-of-service PAs toservice by resetting them.If a PA fails to come back in service, the controller repeatedly tries torestore the PAs to service. Note that regardless of whether the PA comesback in service, the original alarm that caused the problem is stillmaintained in the log. Except for the Out of Service alarms, the only wayalarms can be zeroed is with ALA=0 or a system reset.PA Faults Reported:• PA OUT OF SERVICE ALARM• PA TEMP HIGH ALARM: PA temperature above the Max PA Temp.• PA POWER HIGH ALARM: PA output power above the Max PowerAlarm Point. Following is a list of possible causes:ü Too much gainü Oscillation• PA POWER TOO LO ALARM: PA output power below the MinPower Alarm Point. Following is a list of possible causes:ü PA failureü Problem with one of the RF cables that couple the Pas to the LNA andcombiner/splitters• PA OVER CURRENT ALARM: PA output stage drawing excessivecurrent. Following is a list of possible causes:ü PA failureü Too much gainü OscillationPower Supply Faults Reported:• POWER SUPPLY TEMP ALARM: This alarm count indicates thenumber of 10-minute intervals during which the power supplytemperature exceeded its internally set Max Power Supply Temp.• AC POWER LOST ALARM: This alarm is logged if the AC power islost for a period of time longer than the AC Power Fail duration.• DC VOLTAGE ALARM: The Power Supply Regulation Alarmregisters a ±10% variation in either the +12 V or +26 V supplies. Thevoltages are monitored at the controller board. A monitored supplyvoltage point must be in the alarm condition for at least 1 second beforean alarm is logged. Shorter duration dips below the alarm points areignored.
A. Software ControlPage A-20 MR Booster Manual: Appendices (MN001808-1, 9/99)System Alarm Conditions Reported:• ROM ALARM: Problem in Read Only Memory. (Checked at power-upby computing a ROM checksum and comparing it with a storedchecksum. Note: The CHK command will recompute the ROM checksumand display the stored checksum but will not check for a match.)• EEPROM ALARM: Problem in Nonvolatile Memory. (Checked atpower-up by looking for several "signature bytes" that indicate if datahave ever been written and if gross memory loss has occurred. If thesignature cannot be found, the system tries to write the defaults [and thesignature] to the EEPROM.ü Alarm readings:0 = No problems.1 = Signature not found, but system was able to write itsuccessfully. (All operating parameters will revert to theirdefault values.) Software upgrades usually result in thisreading, since different versions employ different signatures.Repeated occurrences indicate an intermittent EEPROM.• VSWR HIGH ALARM: VSWR is too high in unit with VSWR optioninstalled.• CABINET DOOR OPEN ALARM: This alarm count indicates thenumber of 10-minute intervals during which the cabinet door wasdetected to be open.NOTE: Alarm will not be logged for 30 seconds after an ALA=0 or REScommand. This allows the operator time to disconnect the local terminaland close the door.• GEN PURPOSE ANALOG INPUT ALARM: Indicates the number oftimes the voltage on the general-purpose analog input has gone above orbelow the threshold specified in the Analog Input Alarm State parameter.• GEN PURPOSE DIGITAL INPUT ALARM: Indicates the number oftimes the input has been different from the Digital Input Alarm Stateparameter if enabled.
