Section D. THEORY OF OPERATION
D.1 DESCRIPTION
The MARK-IV VHF Broadband Signal Booster (M4BBDAV) is a stand-alone
Broadband bi-directional & multi-channel two-way radio signal suitable to
drive its internal high-power amplifiers that feed the service-side transmit
signals and/or a fiber-optic distribution.
The system houses multi-carrier linear broadband power amplifiers and
automatic level control. The amplifiers are designed with special linear
characteristics for continuous operation, 100% duty cycle 24 hours/7 days a
week. Its modular construction allows easy access to the amplifier modules
and power supply.
It has a maximum gain around 60 dB across the band. The output power
amplifier P1dB Compression point is around 20 Watts (+43 dBm). They also
have an automatic gain control range greater than 25 dB.
The amplifiers modules are bolted down onto a heat-sink base. These heat
sinks have adequate capacity to dissipate five times the maximum
anticipated heat being generated by the amplifiers. It is recommended the
temperature of the room be maintained below 800 F to assure the longest
possible life of the amplifier transistors. The power supply has +28 VDC module
for the amplifiers, equipped with over current and over voltage protection
among other features. It will immediately drop the supply voltage to prevent
damage to other components.
The unit’s operational parameters are stored in the non-volatile memory of
the embedded controller; this allows the booster to operate on a standalone
basis. The built-in Web Server provides a Graphical User Interface (GUI) to
ease in remote monitoring & control. Access is obtained via a PC’s Web
Browser and a TCP/IP connection to the Unit. The system can be connected
directly to a PC computer or can be plugged into the local area network.
Discrete Digital I/O alarms are available for external monitoring.

F.1.2 CONNECTING SYSTEM TO LOCAL AREA NETWORK
Use standard straight-thru cable for network switch/hub connection.
To connect system to LAN, it is necessary to know the subnet the PC
computer is currently plugged into.
If no network is available the user shall remain using the crossover
interconnection
Figure 8 – System connected into local area network.
The following steps are necessary to connect system to LAN:
1. Connect the radio system and the computer together by means of
ethernet switch.
2. The radio system has a default IP address (S.M. 255.255.255.0).
3. Configure the computer’s IP address within the same subnet as the
radio system, 192.168.100.X (for example 192.168.100.75, S.M =
255.255.255.0) as shown in previous section.
4. Open a web browser and access the equipment by typing, in the
address bar, the IP address of the radio equipment.

limits the composite multi-carriers output power
from exceeding the preset level. The indicator is
ON when the MCPA is limiting; OFF otherwise. If the
option is disabled in Main Settings, the Limiter
Status will show DISABLED.
Amplifier Status
Indicates if the MCPA Output is “Unmuted”,
“Muted” or “Muted by Alarm”(in case the MCPA
Reflected Power Alarm is “Triggered” or
“Latched” and the option “Enable Automatic
Mute upon Reflected Power Alarm” has been
selected in Main Settings page).

Start Level (dBm)
The “Start Level” is a read-only value; it is
automatically set by the system in order to
comply with expected Gain and Set Point
Level.
It is the input Automatic Level Control limiter
threshold. If the Input RF Composite Power is
greater than iALC Start Level, it will be
attenuated to avoid system saturation.
Turn-off iALC stage
Turn-off iALC stage output power causing the
output power being down.
F.2.2.2 MCPA Control:
For the “Output MCPA Mute” and “Reset Reflected Power Alarm Reset”
commands, the user can set the preferred control method by choosing
Software or Hardware in the “Control by” field.
a. If the user chooses hardware control, the controller will respond to the
opto-isolated inputs located in the ECM I/O DB25 Connector and the
software commands for these two parameters will have no effect.
The Reset Reflected Power Alarm command mapped to ECM I/O DB25
Connector can be controlled through pins 7 and 8 for both Service Side
(DL Tx) and Donor Base (UL Tx) outputs.
The Power Amplifier Mute command mapped to ECM I/O DB25
Connector can be controlled through pins 5 and 6 for both Service Side
(DL Tx) and Donor Base (UL Tx) outputs.
When “Control by Hardware” is selected the UL and DL MCPAs are
automatically un-muted unless the corresponding opto-isolated input is
energized.
Output MCPA Mute
Mute/un-mute MCPA
Reset Reflected Power Alarm
Clear the Reflected Power Alarm Latch.

b. On the other hand, if the user chooses software control, the controller
will respond to these software commands instead of to the opto-isolated
inputs.
Also, there are four M4-BBDA settings that can be controlled using software
commands:
Output MCPA ALC Limit
Level
Output limiter set point 30 to 37 dBm.
Output MCPA ALC Enable
Check-box to enable/disable the output ALC.
Enable Automatic Mute
upon Reflected Power
Alarm
Check-box to enable/disable automatic
MCPA mute upon excessive reflected power.
Enable Reflected Power
Alarm Status Latch
Check-box to enable/disable the alarm status
latch.
F.2.2.3 Updating operational settings
Using the checkboxes click to check/un-check.
Press enter or “Apply” button for the system to validate the data and
apply changes.
o If the value is not valid, an error message will be displayed (see
Figure 11) and the new value will be not accepted keeping the
previous value.
The current state applied to system is saved to the controller’s internal
nonvolatile memory for effective recovery after a power loss or system
reset.
