In the downlink path, the BTS signals are received by the donor antenna of the repeater. After the circulator, the
signals are sent to downlink filter and then the LNA module for pre-amplification and to the digital RF integrated
module for digital filtering and frequency conversion. Then the DL signals will be sent to the downlink PA to
amplify power, and filter via downlink filter, the circulator, and last, the signals are transmitted at the MT port to
the service antenna.
In the uplink path, the mobile signals are received by the service antenna. After the circulator, the signals are
sent to uplink filter, and then to LNA, digital integrated module for digital filtering, then to the PA for power
amplification and to the uplink filter, the circulator, after that, the uplink signals are sent to the donor antenna for
transmission back to the BTS.

EQUIPMENT CONSTITUTION
The typical PS BDA unit consists of the following components:
Downlink Power Amplifier (DPA): It provides power amplification for DL branches.
Uplink Power Amplifier (UPA): It provides power amplification for UL branches.
Main Control Unit (MCU): The MCU is used to monitor and control the operation of the repeater. It also
provides the communication interface for remote control and status indication. LED indicators provide the
operation status of the MCU.
Downlink Filter: The filter is used to restrain the uplink signals to achieve a better isolation between downlink
path and uplink path, to make sure the device can work in a normal duplex mode.
Uplink Filter: The filter is used to restrain the downlink signals to achieve a better isolation between downlink
path and uplink path, to make sure the device can work in a normal duplex mode.
Digital Integrated Module: Consists of RF module, digital process module and monitoring modules. The RF
module amplifies and converts the RF signal to IF signal. The Digital process module converts the IF signal into
baseband signal via AD conversion and extraction, and filtering. After that, the IF signal will be amplified and
converted to an RF signal by the RF module for RF filtering and amplification. The Monitoring module monitors
and controls the system parameters and it is the interface for both remote monitoring and local commissioning,
and at the same time control the charge and discharge of the backup battery.
Power Supply Unit (PSU): The PSU converts the input voltage into a stable DC supply to provide power for
the internal functional modules.

WARNINGS AND ALERTS
Radio Frequency Energies
There may be situations, particularly for workplace environments near high-powered RF sources, where
recommended limits for safe exposure of human beings to RF energy could be exceeded. In such cases,
restrictive measures or actions may be necessary to ensure the safe use of RF energy.
High Voltage
The equipment has been designed and constructed to prevent, as far as reasonably practicable danger. Any
work activity on or near equipment involving installation, operation or maintenance must be, as far as
reasonable, free from danger.
Where there is a risk of damage to electrical systems involving adverse weather, extreme temperatures, wet,
corrosive or dirty conditions, flammable or explosive atmospheres, the system must be suitably installed to
prevent danger.
Protective Earthing
Equipment provided for the purpose of protecting individuals from electrical risk must be suitable for the
purpose and properly maintained and used.
Handling Precautions
This covers a range of activities including lifting, lowering, pushing, pulling, carrying, moving, holding or
restraining an object, animal or person from the equipment. It also covers activities that require the use of force
or effort, such as pulling a lever, or operating power tools.
Where some of the abovementioned activities are required, the equipment must be handled with care to avoid
being damaged.
Electrostatic Discharge (ESD)
Observe standard precautions for handling ESD-sensitive devices. Assume that all solid-state electronic
devices are ESD-sensitive. Ensure the use of a grounded wrist strap or equivalent while working with
ESD-sensitive devices. Transport, store, and handle ESD-sensitive devices in static-safe environments.

SITE PLANNING CONSIDERATIONS
3.2.1 SITE PLANNING
Site Considerations
Outdoor equipment are designed to be waterproof, rainproof, and with snow protection. Temporary protection
should be taken when the equipment enclosure is opened for installation or maintenance in an outdoor
environment. The equipment must not be opened for installation or maintenance in bad weather (e.g. gale,
storm rainfall, extreme temperatures and high humidity)
Installation Location
Mounting surface shall be capable of supporting the weight of the equipment.
In order to avoid electromagnetic interference, a proper mounting location must be selected to minimize
interference from electromagnetic sources such as large electrical equipment.
Environmental
Humidity has an adverse effect on the reliability of the equipment. It is recommended to install the equipment in
locations having stable temperature and unrestricted air-flow.
The installation location for the product should be well ventilated. The equipment has been designed to operate
at the temperature range and humidity level as stated in the product specifications in the datasheet.
Direct sun light exposure to the equipment should be avoided. Provide additional shelter if necessary.
Power Supply
The power supply unit (PSU) provides power to all modules within the equipment. Depending on the product
variant, it is recommended that the PSU be operated on a dedicated circuit breaker or fused circuit.
Grounding Requirement
Verify that the equipment has been well grounded. This includes antennas and all cables connected to the
system. Ensure lightning protection for the antennas is properly grounded.
Cable Routing
Depending on equipment configuration, a variety of types of cables are required. Where applicable, ensure
cables are properly routed and secured so that they are not damaged.
Manual Handling
During transportation and installation, take necessary handling precautions to avoid potential physical injury to
the installation personnel and the equipment.
ENU STATUS : 1-0-1
Copyright - refer to title page
Page 14
INSTALLATION GUIDE FOR RX-4122
3.2.2 INSTALLATION CHECKLIST
Working space available for installation and maintenance for each mounting arrangement. Ensure
unrestricted airflow.
Ensure earth ground point is within reach of the ground wire.
Ensure a power source is within reach of the power cord and the power source has sufficient capacity.
Where appropriate, ensure unused RF connectors are terminated.
Do not locate the equipment near large transformers or motors that may cause electromagnetic
interference.
Reduce signal loss in feeder cable by minimizing the length and number of RF connections.
Ensure VSWR of antennas system < 1.5:1.
Ensure equipment will be operated within the stated environment (see datasheet)
Observe handling of all cables to prevent damage. Donor antenna should have a narrow beamwidth and
positioned in line-of-sight (LOS) to the donor BTS site so that the donor signal level is maximized. This
allows the use of minimum gain to achieve the maximum DL output power. The UL gain is typically set
lower than or equal to the DL gain to minimize noise interference to the donor BTS
Service antennas should be selected based on the type of service area, e.g., indoor antenna for indoor
application, and panel antenna for outdoor application.

3.4.3 GROUNDING CONNECTION
Ground Connection
To ensure safe operation of the product, a ground (earth) connection is required. For single phase AC power
source, the product must be grounded by connecting the “earth wire” of the power cord to the ground terminal
of the AC supply. For operating this product with DC power system (such as rectifiers), the product should not
be connected to power systems that switch open the return lead because the return lead could function as the
ground (earth) connection for the equipment.
Protective Ground Connection
The enclosure must be grounded securely by connecting a copper wire (CSA 16mm2) to the grounding terminal
on the equipment/rack, and the other end to a protective ground (i.e. building earth point). An internationally
acceptable color code of the ground connection wire is green/yellow.
Such a ground connection implements the “Protective Ground Connection”, and must be connected to the
equipment at the designated ground point. In general, do not connect the supply before establishing an
adequate ground (earth) connection.
Construct the ground wire, and use appropriate crimp connectors where necessary. Locate and connect the
equipment grounding terminal to a protective ground (i.e. building earth point).

7 APPENDICES
7.1
APPENDIX A:
Antenna installation:
Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used for this
transmitter must be mounted on permanent structures.
The FCC regulations mandate that the ERP of type B signal boosters should not exceed 5W, this is equivalent
to 8.2W EIRP (39.1dBm).
Therefore the max antenna gain allowed for this type of signal booster should be limited to the values given by
equation 1 (below) for the service antenna.
Equation (1) – Max Service antenna gain
Max Service antenna gain (dBi) = 39.1-(36dBm-# of antennas in dB – cable losses in dB).
For example:
No. of Antennas
10
Cable losses
Max Allowed Antenna Gain
39.1-(36-6-3)=12.1dBi
39.1-(36-0-3)=6.1dBi
39.1-(36-10-3)=15.1dBi
Compliance with FCC deployment rule regarding the radiation of noise
Good engineering practice must be used in regard to the signal booster’s noise radiation. Thus, the gain of the
signal booster should be set so that the ERP of the output noise from PS BDA should not exceed the level of
-43 dBm in 10 kHz measurement bandwidth.
In the event that the noise level measured exceeds the aforementioned value, the PS BDA gain should be
decreased accordingly.
In general, the ERP of noise on a spectrum more than 1 MHz outside of the pass band should not exceed -70
dBm in a 10 kHz measurement bandwidth.
RX-4122 PS BDA has a noise level of -21 dBm in 100 kHz (equals to -31dBm in 10kHz) measurement at 1 MHz
spectrum outside the pass band of BDA and an in-band noise level at around -50 dBm in a 10 kHz bandwidth.
Therefore, the noise at the antenna input port should be calculated based on equation (2).
Equation (2) – Input Noise to service antenna
Input Noise to service antenna:
-31dBm – antenna splitter losses in dB – out of band rejection of filters - cable loss in dB
For example: in band noise
RX-4122 PS BDA connected to 10 service antennas with a 100m long ½ inch cable.
Losses of such a cable with the connectors = ~ 12dB
Assuming 10 service antennas: antenna splitter losses = 11 dB
Based on equation (2) Input antenna noise (to the antenna) = – 51 – 12 – 0 –11=-74 dBm ERP
ENU STATUS : 1-0-1
Copyright - refer to title page
Page 49
INSTALLATION GUIDE FOR RX-4122
The in-band input noise to the antenna should be – 51 – 12 – 0 – 11= -63dBm ERP
For example: Out of band noise
RX-4122 PS BDA connected to 10 service antennas with a 100m long ½ inch cable.
Losses of such a cable with the connectors = ~ 12dB
Assuming 10 service antennas: antenna splitter losses = 11 dB
Out of band rejection of filters: more than 45dBc
Based on equation (3) Input antenna noise (to the antenna) = – 31 –12 – 45 – 11= – 99dBm ERP
The Out of-band input noise to the antenna should be – 31 –12 – 45 – 11= – 99dBm ERP
Conclusion:
Good engineering practice requires that in general when the out of band noise measured at the service
antenna input is more than -70 dBm per 10 kHz measurement bandwidth, an external band pass filter should
be added to attenuate the out of band noise level.
All Comba BDAs include high selectivity duplexers and filters to attenuate the out of band noise.
Compliance with FCC Part 90.219 (d)(6)(i)
The deployment rules require that the ERP of intermodulation products should in general not exceed -30dbm.
This is not a formidable task since in the vast majority of the passive DAS installations; the signal loss in the
DAS due to splitting to multiple antenna and cable losses is significant.
As well as the above RX-4122 PS BDA is more likely to be used in a multicarrier environment (more than 2
carriers), which in turn will reduce the intermodulation products produced by the device.
The following statement is already in the user manual to highlight the requirement to the installer for the
instances where the above does not reduce the ERP of the intermodulation products to -30dBm.
‘The installation procedure must result in RX-4122 PS BDA complying with FCC requirements 90.219(d). In
order to meet FCC requirements 90.219(d), it may be necessary for the installer to reduce the UL and/or DL
output power for certain installations.’
