2.1
Introduction
This section describes the basic functions and features of an MR Booster, including:
• System overview
• Theory of operation
• System components
2.2
System Overview
The MR Booster is a broadband, bi-directional amplifier (BDA) used to extend the
coverage area in a wireless communications network. The booster is specifically
designed to interface with the MIKOM MR series repeater. It can also be used with
an existing repeater or a base transceiver station (BTS) that needs a downlink power
boost.
Figure 2-1 illustrates a typical MR Booster application with a repeater, and Figure 22 illustrates a typical application with a BTS. The booster is connected directly to the
coverage antenna port from the repeater or BTS and boosts the downlink signal
power while maintaining dynamic range on the uplink. The booster performs several
basic 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 mobile
antenna, amplified by an LNA, and passed directly to the repeater or BTS.
• Control and alarm monitoring is maintained by MR repeater software or through
two relay contact outputs from the booster.
• Power supply and power amplifier soft-fail redundancies offer increased
reliability.
• A separate uplink diversity path is available as an option.
• Downlink output VSWR monitoring is available as an option.

Theory of Operation
A 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 in
Figure 2-1.
2.3.1
Downlink path
Duplexed RF from the repeater’s coverage antenna port is connected to the
booster downlink port. The repeater duplexer then routes the downlink signal
frequencies to the PA combiner/splitter module.
MR Booster Manual (MN001808-1, 7/99)
Page 5
2. System Description
The downlink signal frequencies are then routed to the PA combiner/splitter
module by the repeater duplexer. In the high-power option, the RF is split
into four separate paths by the hybrid combiner/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 RF PAs.
NOTE: The multiple amplifiers provide soft-fail redundancy to maintain
minimum output power capability should one or more fail in the field.
The PA outputs are summed in a second combiner/splitter, then routed to the
mobile-side duplexer. The duplexer routes the downlink RF output to the
coverage antenna, which transmits to handsets in the booster coverage area.
2.3.2
Uplink path
Mobile handset transmissions are received at the mobile duplexer port and
routed to the LNA input by the mobile duplexer. The amplified LNA output
is then routed to the repeater duplexer, which is connected to the installed
repeater’s coverage antenna port.
A diversity option offers a second, identical uplink path when diversity is in
use in the donor BTS or repeater.
2.3.3
System control
Control functions include PA keying, fan control, and uplink attenuation
setting. Monitored parameters include PA output power, status, system
temperature, power supply temperature, DC output voltage and status, and
input power source (ac or dc).
Resident software can be accessed via the supplied serial interface cable with
a laptop computer and terminal-emulation software to initialize and customize
the unit during installation or to perform troubleshooting.
The booster can be remotely controlled after installation with a Mikom MR
series repeater via the I2C bus interface cable.
For other applications, or if remote control is not required, a pair of relay
closure outputs from the booster can be user-configured and routed to the
donor system to flag system problems after installation.

2.4
System Components
2.4.1
Power Supply
The MR Booster provides two high-efficiency power supplies with 26 VDC
and 12 VDC outputs (see Figures 2-4 and 2-5). The 26 V output is split
evenly between the system PAs to provide soft-fail redundancy. The 12 V
output is diode-connected at the controller and the LNAs, ensuring that both
will function if a power supply fails. The power supply has thermal
shutdown capability.
The AC supply input is auto-ranging to handle 115 and 220 volt, 50 or 60 Hz
systems. During loss of AC mains, the booster will automatically switch over
to the DC input for operation with a BBU.
2.4.2
Downlink Power Amplifier
The downlink power amplifiers (see Figure 2-4) provide low distortion
amplification of downlink RF signals using proprietary feedforward
correction techniques. After duplexer, splitter and combiner losses, the PAs
provide 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. To
provide maximum output power and soft-fail redundancy, the downlink power is
shared between either four (high-power option) or two (medium-power option)
PAs. Each PA provides output power and temperature status information to the
system controller and provides both overcurrent and overtemperature protection
circuitry.
2.4.3
Logic Controller Board
The logic controller board (see Figure 2-4) monitors and controls internal
booster functions, and provides alarms to the donor system. The controller
contains an I 2C bus interface for remote control by a Mikom MR series
repeater. The controller is powered by the 12 VDC supply.
System configuration information is retained in an on-board EEPROM. For
installation or troubleshooting, the board-resident software can be accessed
from an MR repeater, or from an on-site laptop computer. The controller can
set:
• uplink gain
• PA key/unkey
• fan speed control (high/low/off)
MR Booster Manual (MN001808-1, 7/99)
Page 9
2. System Description
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
• VSWR input (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-configured
during installation. The outputs are normally open relay contact pairs, which
are closed when no alarm condition is present. These signals are provided on
four of the seven pins of a terminal block on the controller board.
2.4.4
PA Combiner/Splitter Module
The PA combiner/splitter module (see Figure 2-4) splits the input signal,
distributes it to the PAs and combines it after amplification. Identical hybrid
design is used to ensure maximum amplitude and phase matching of the
downlink signal.
2.4.5
Uplink Low Noise Amplifier
The LNA (see Figure 2-4) maintains dynamic range for uplink mobile
signals. The LNA provides low noise figure and high input IP3 so the booster
does not decrease sensitivity or increase distortion in the system.
The gain of the LNA chain after duplexer and cable losses is nominally 20 dB
with the uplink attenuation set to 0 dB. Using the internal software, the gain
can be reduced by increasing the attenuation in 1 dB steps up to 15 for
optimal IP3, or where equal uplink and downlink booster gain is not
necessary. The same LNA is used in the diversity option and the attenuation
setting is ganged so each uplink path is set for equal gain.
Page 10
MR Booster Manual (MN001808-1, 7/99)
2. System Description
2.4.6
Duplexers
The duplexers (see Figure 2-4) provide isolation between uplink and
downlink paths, and band-limit the signals that are either passed to the donor
hardware, or transmitted at the mobile antenna. The small repeater duplexer
provides adequate UL/DL isolation. The mobile duplexer offers low insertion
loss to maximize downlink output power and uplink noise figure. Forward
and reverse directional coupler outputs are provided on the mobile duplexer.
The coupler outputs are routed to the VSWR module when that option is
installed.
2.4.7
RF Cables
The RF cables are a critical part of the MR Booster, particularly in the
downlink function. Low loss provides maximum output power and cable
propagation delays must be properly controlled so that the amplifiers are
combined with low phase error.
CAUTION: Never substitute RF cables in the booster. Use only
proper MIKOM part numbers.
2.4.8
Fan Assembly (High-power only)
Dual DC fans (not shown) maintain a low cabinet temperature in the high
power option. The fans are sealed to withstand all weather conditions. The
plenum and ducting structure of the booster is designed to move air over all
heat fins, even if one fan fails. The fans can be disabled or operated at low
speed for climates where over-heating will not be a problem. The logic
controller provides the fan interface.
2.4.9
VSWR Module (Optional)
The VSWR module (not shown) monitors the downlink output VSWR. The
customer is alerted to potentially damaging antenna mismatch. The module
receives ± 12 VDC from the controller and coupled outputs from the mobile side
duplexer. The coupled signals are processed the output VSWR is routed to the
logic controller.
MR Booster Manual (MN001808-1, 7/99)
Page 11
2. System Description
2.4.10 Downlink Driver Amplifier (Optional)
An ultra-linear driver amplifier (not shown) provides more downlink gain or
boosts the linear output power. Contact technical support for availability and
details.
Figure 2-5. Input/output panel
2.4.11 Input/Output Panel
All system inputs and outputs are accessible from the bottom panel of the
cabinet (see Figure 2-5). All RF connectors are 7-16 female bulkhead. All
unused RF ports have gasketed plates covering the connector cutout.
Control, alarm, and power connections are made via multi-conductor cables
routed through weatherproof glands. Unused glands are filled with removable
plugs.
NOTE: The customer is responsible for ensuring a weatherproof seal on
glands not set up in the factory.
Following are the descriptions of the available I/O connections:
• Repeater Duplexer or DL (optionally repeater DL only): Connected to
the repeater’s mobile coverage antenna port. It accepts downlink signals
from the repeater and outputs the uplink RF to the repeater.
NOTE: If the MR Booster must interface with a non-duplexed system,
this port can be used to route the downlink output from the repeater to the
booster.
• Repeater UL (optional): This port is used only when the repeater has
non-duplexed mobile input and output. The uplink output is then routed
through this connector from the booster to the repeater.

System Optimization
Refer to Figure 3-5 for an example of an application in which the MR Booster is used
to boost a repeater. For additional information regarding system optimization, please
contact Mikom technical support at 1 (800) 800-3224.
3.5.1
Downlink Gain Setting
The downlink gain is generally determined by the output power that provides
coverage of the hole that the MR Booster is filling. This power should not
exceed the specifications in Section 6 for differing technologies and number
of carriers. The gain of the repeater must be adjusted via the operational
software so that the desired output power equals the system gain (repeater
plus booster) plus the input power received from the BTS.
The input power can be determined from the downlink RSSI reading of the
repeater for each applicable RF channel. For greatest accuracy, the factory
test data sheet enclosed with the MR Booster can be used to determine the
booster gain near each channel of interest.
3.5.2
Downlink Power Measurement
To ensure that the proper output power is reached, measure the composite
power coming out of the mobile duplexer port. Use a power meter capable of
handling 100 mW with a 30 dB, 60 W power attenuator on the mobile
connector for an accurate measurement without damage. The composite
power 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.
MR Booster Manual: (MN001808-1, 7/99)
Page 25
3. Installation
3.5.3
Uplink Gain Setting
In most cases, the repeater gain is adjusted to make the uplink gain equal to
the downlink gain to maintain a balanced link. Adjust the repeater gain, leave
the MR Booster LNA gain set to maximum, and the overall system noise
figure is minimized.
In cases where unusually strong in-band interferers are present, it may be
necessary to decrease the LNA gain in order to increase the overall system
input intercept point. The amount of attenuation added depends on the
required system intercept point, – the maximum allowable system noise
figure and the dynamic range of the repeater.

System Monitoring Commands
The MR Booster software monitors the status and performance of the system through
simple commands. Each command is entered at the command prompt (>). The
following commands are described in this section:
• SSS (Show System Status) Command
• ALA (Alarm Report) Command
• PWR (PA Power Display) Command
• REV (Show Software Revision) Command
Page A-14
MR Booster Manual: Appendices (MN001808-1, 7/99)
A. Software Control
A.5.1 SSS (Show System Status) Command
Entry: At the > prompt, enter SSS press Enter.
Purpose: Lists a one-page report of selected MR Booster operating
parameters, along with the conditions of inputs that are monitored, then
returns to the command entry level. Figure X-X shows a sample SSS report.
Items listed in the report are described on the following pages.
Reported Items:
• BOARD MODE: Operating mode of each board:
ü
ü
ü
Enabled: Indicates the board is actively repeating signals in both
forward and reverse directions.
Standby: Indicates the board is OK, but not currently Active due to a
problem with another element in the system. Normally, a board that is
Standby will automatically go back to Active if the problem on the
board or PA is cleared up.
Disabled: Indicates either that the board status is set to None or
Disabled (i.e., the board has been disabled by the user) or that the
board is Disabled due to an alarm condition. If the latter case is true,
the ALA command will show an OUT OF SERVICE alarm that
caused the out-of-service condition.

• BOARD TYPE: Board type as read from the actual hardware. The
installed boards have a built-in personality identifier that is read and
reported. Board types are indicated as follows:
ü
Wideband boards:
- Cellular: Indicates the band and service the board is designed to
support.
- 1.25 MHz: Indicates the bandwidth of the filters on the board.

A.5.2 ALA (Alarm Report) Command
Entry: At the > prompt, enter ALA press Enter.
Purpose: Displays a report of the number of alarm conditions that have
occurred since the last system reset, then returns to the > prompt. Figure X-X
shows a sample ALA report. Reported alarms are described on the following
pages.
>ala
to come . . .
Figure X-X. Sample ALA Report
Reported Alarms Description:
• Counts stop at 63.
• All counts are zeroed after a power reset or a RES command. Counts may
be zeroed by entering ALA=0.
Page A-16
MR Booster Manual: Appendices (MN001808-1, 7/99)
A. Software Control
• 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 given
alarm is logged, at most, one time in 10 minutes. The alarm counts may
be interpreted as the number of 10-minute intervals in which the alarm
occurred.
There are two exceptions to this: the board and PA Out of Service alarms,
which are really not logs at all, but reflect the current condition of the
board or PA.
• Automatic Restore to Service: If an alarm condition causes a board or
PA to be taken out of service, the system will continue to process calls
using available boards and PAs until no calls are up. At that time, the
controller will attempt to restore out-of-service boards to service by
resetting the boards.
After the boards reset???, the controller power-on diagnostics are run on
all boards and PAs. These diagnostics check for all alarms that may cause
a board or PA to be out of service, and if an alarm of that type occurs, the
board or PA remains out of service. If a board or PA fails to come back in
service, the controller repeatedly tries to restore boards or PAs to service
(during times when no calls are up) up to 10 times, the last seven of
which are spaced at least 1 hour apart. Note that regardless of whether the
board or PA comes back in service, the original alarm that caused the
problem is still maintained in the log. Except for the Out of Service
alarms, the only way alarms can be zeroed is with ALA=0 or a system
reset.
PA Alarms Reported:
• PA OUT OF SERVICE ALARM: PA currently out of service. If the
measured PA power exceeds the Maximum Power AGC Threshold level,
the controller will reduce the gain in 4 dB steps, as long as the condition
persists, down to the minimum setting. If the output power still exceeds
the Maximum Power AGC Threshold, the PA will be taken out of service.
(If the PA mode displayed by the SSS command is DISABLED, the PA
has been taken out of service.)
MR Booster Manual: Appendices (MN001808-1, 7/99)
Page A-17
A. Software Control
When a PA goes out of service, the MR Booster will attempt to bring it
back into service by re-initializing the RF hardware, including the
boards??? and the PAs. Because an out-of-service PA is usually due to
an oscillation condition, the system does not attempt immediately to bring
it back. Rather, the system will attempt a restore-to-service once each
hour, as long as the PA continues to go back out of service. After seven
such attempts, the system will discontinue restore-to-service attempts to
that PA, leaving it out of service. However, if another board or PA goes
out of service, it will trigger its own set of restarts, any of which might
bring back any or all out-of-service boards or PAs.
• PA TEMP HIGH ALARM: PA temperature above the Maximum PA
Temperature Alarm Point parameter.
• PA POWER HIGH ALARM: PA output power above the Maximum
Power Alarm Point parameter. Following is a list of possible causes:
ü
ü
ü
ü
Improper setting of the PA Power High Alarm Point with respect to
the PA Power AGC Threshold
Failure of the AGC algorithm to keep the power in check
Too much gain
Oscillation
• PA POWER LOW ALARM: PA output power below the Minimum
Power Alarm Point parameter at a time when RSSI and gain are sufficient
to cause that much power. Following is a list of possible causes:
ü
ü
ü
PA failure
Board failure (either low gain or inaccurate RSSI reporting)
Problem with one of the RF cables that couple the boards and PAs
System Alarm Conditions Reported:
• ROM ALARM: Problem in Read Only Memory. (Checked at power-up
by computing a ROM checksum and comparing it with a stored
checksum. Note: The CHK command will recompute the ROM checksum
and display the stored checksum but will not check for a match.)
• NOVRAMALARM: Problem in Nonvolatile Memory. (Checked at
power-up by looking for several "signature bytes" that indicate if data
have ever been written and if gross memory loss has occurred. If the
signature cannot be found, the system tries to write the defaults [and the
signature] to the NOVRAM.

• DC VOLTAGE LOW ALARM: The +12 volt supply went below the
associated Low Alarm Point. The voltages are monitored at the controller
board. A monitored supply voltage point must be in the alarm condition
for at least 1 second before an alarm is logged. Shorter duration dips
below the alarm points are ignored.
• AC SUPPLY LOST ALARM: This alarm is logged if the AC power is
lost for a period of time longer than the AC Power Lost - Alarm Point
duration.
• POWER SUPPLY TEMP ALARM: This alarm count indicates the
number of 10-minute intervals during which the power supply
temperature exceeded its internally set Max Operating Point.
• CABINET DOOR OPEN ALARM: This alarm count indicates the
number of 10-minute intervals during which the cabinet door was
detected to be open for at least 1 second.
NOTE: Alarm will not be logged for 10 minutes after an ALA=0 or RES
command. This allows the operator time to disconnect the local terminal
and close the door.
• EXT. ANALOG ALARMS: Indicates the number of times the voltage
on the general-purpose analog input has gone above or below the
threshold specified in the Ext. Analog Input Alarm State parameter. An
external analog input alarm condition must persist for at least 1 second
before an alarm is logged. Shorter durations are ignored.
• EXT. DIGITAL ALARMS: Indicates the number of times the input has
been different from the Ext. Digital Input Alarm State parameter if
enabled. An external digital input alarm condition must persist for at
least 1 second before an alarm is logged. Shorter durations are ignored.
