4.3 System configuration and functions
The iDEN (Integrated Digital Enhanced Network) RF repeater is composed of PSU(Power
Supply Unit), RCU(RF Control Unit), Up / Down Converter Module, PAU(Power Amplifier Unit),
Filter, and Isolator Check module.
< Fig. 10 > System configuration
iDEN
4.3.1 PSU (Power Supply Unit)
This is used to supply stable DC power to each device provided with active elements through
A/D conversion and D/D conversion by receiving AC power, uses semiconductors for industry or
higher in terms of major activation elements, is mechanically strong, and satisfies all electrical
characteristics. A power used, it is supposed to receive 108~127VAC, convert to DC 3.8V, DC
7V, DC 12 and DC 27V, and then use it.
And, the controller uses replaceable batteries and improper replacement can bring about
explosion, so dispose of the used batteries safely.
4.3.2 Controller
A controller is composed of RCU(RF Control Unit) and NCU(Network Control Unit) and plays a
role to monitor and control the status of each module of iDEN repeater.
The RCU(RF Control Unit) is connected to GUI through DEBUG port and can collect and control
the status monitoring information of modules.
NCU(Network Control Unit) enables the upper NMS(Ethernet) communication through the RJ-
45 port and can monitor and control status. The front face of NCU is provided with LED to
display the status so as to confirm existence of abnormality in modules easily.
CAUTION※
Improper replacement of batteries can bring about risk of explosion.
Dispose of used batteries according to manufacturer’s instructions.
4.3.3 Filter
This is connected to donor ANT of iDEN repeaters as a cavity type of filter and has only the
desired bands among the signals from the base station(EBTS) received through antenna pass
selectively, so as to remove other bands, secure isolation between DL and UL enough, and
have only the bands to service inputted through the LNA terminal. Besides, in the reverse
direction(Up Link), it works to minimize the spurious radiation power generated by PAU.
4.3.4 Up / Down Converter Module
The Up / Down Converter Module is composed of a down converter, up converter, and digital
filter of variable bandwidth from the filter to the PAU input in the down link and up link of iDEN
repeaters. Besides, this is composed of a pair of equal structure in order to deal with two bands
of 900M and 800M.
iDEN
The up/down converter of Down Link was realized with a digital filter through conversion and
A/D conversion with IF frequencies(62.5MHz) for the base station(EBTS) signals inputted
through the LNA part.
This picks up an excellent roll off characteristic with a digital filter, minimizes influence on other
signals by intercepting other neighbor bands and signals, and is improved to remove and
separate spurious waves.
And, the Up Link takes a roll off characteristic of a SAW filter by converting RF signals at the
inputted terminal to IF frequencies(70MHz) through LNA differently from the Down Link,
minimizes influence on other signals by suppressing neighbor signals, and is improved to
remove and separate spurious waves.
This suppresses leakage of local signals to the input terminal by inserting a band passage filter
at the front side of mixers. The mixer minimizes IMD components of a system by applying an
element that has a characteristic of High IP3 and minimizes influence on the next step by
maintaining linearity. The base station(EBTS) signal converted to a IF frequency is recovered to
the original frequency through the up converter.
The local step for IF conversion is designed to minimize phase noises in order not to reduce
quality(ρ value) of waveform that can take place during the conversion process of signals.
The RF block of the up/down converter of the down link performs AGC and ALC functions to
protect equipment during application of over input to the iDEN RF repeater, enables the on/off
function according to necessity from users, and has an automatic compensation function of
gains with respect to the temperature of a system.
4.3.5 PAU (Power Amplifier Unit)
PAU applied elements with reliability, durability, and good and high P1dB by considering the
spurious characteristics, is always monitoring the output by being connected to the control part
of a system, enables reporting to its superiors during occurrence of major items, and enables
the on/off of PAU operation according to the necessity from users.
The Down Link PAU amplifies iDEN signals to a proper output level and provides the VSWR
information of repeater output level and output port for the Control board.
Besides, this monitors the normal operation status of modules by providing Control boards with
the information on its temperature detection and device failure.

8. System Installation
8.1 Confirmation of System Components
a. Check the following matters during installation for normal operation of equipment.
b. Check existence of abnormality to see if the appearance of repeaters(RF connector), etc.
was deformed due to damage to the repeater packing materials during equipment
transportation.
c. Check if equipment components coincide with one another and check if the installation
place satisfies the working temperature and humidity of the equipment defined in the
product standards.
d. Confirm the input signal conditions of the equipment defined in the product standards.
8.2 Precautions during Installation of the System
In order to avoid occurrence of dangerous situations during installation of repeaters, be sure to
comply with the provided instruction manual by all means.
Especially, the power cord of this repeater is of an eternal connection type, so an easily
accessible power interruption device should be installed in the indoor wiring, and there should
be an easily accessible socket-outlet near the repeater.
Sequ
ence Description Precautions
1
Donor ANT attachment and
feeder cable installation
Service ANT or LCX installation
• When installing cables, perform the work so that there may
be no damage to the crust.
• Protect the connection part such as connectors, etc. with
insulation tapes in order to prevent invasion of moisture, etc.
• When installing the feeder cable, minimize the environmental
influence.
2 Installation of antenna for
donors
• Avoid twist in the antenna direction after construction by
fixing it rigidly by considering wind speed by regions.
3 Arrangement of power cables
and RF cables
• Prevent cable damage due to bending or extension of
cables.

9. System Setup and Checkup
9.1 Check Items during Opening
9.1.1 Check Items before Opening
(１) Check the normal power of AC108~127 VAC and then check existence of abnormality
in power cables.
(２) Check if the donor RF input signal from outside is in a normal level.
Caution: If a system is operated without confirming input signals, serious damage may ※
be caused to the amplification elements due to saturation of output signals, so
operate the equipment after checking the input signal level by equipment and
the ALC ON status of equipment(ALC ON during product shipment) by all means.
(３) Plug AC108~127 V into the power connector of equipment and then turn on the
equipment power switch.
(４) Confirm existence of abnormality by checking the status of alarm LED lighting in the
GUI table or repeater front plate through notebooks.
(５) If the forward RF input signal from outside is judged to be in a normal level, turn off the
power switch of repeaters, connect the ANT feeder cables and service ANT(overhead
cable) to the input/output port of repeaters and then turn on the power switch of
repeaters again.
Caution: Make a connection by paying attention so that forward and backward ports may ※
not be changed for each other.
9.1.2 Check Items after Opening
(１) Confirm existence of abnormality by checking the alarm LED lighting status of repeaters.
(２) Check whether the RF input/output value on NMS is normal or not using GUI.
(３) After about 10 minutes passes after turning on the repeater power, measure the
spurious wave characteristic, etc. of forward and backward output of repeaters using
spectrum waveform analyzer by using the coupling terminal beside each input/output
port of repeaters and confirm the normal operation status of repeaters.
(４) After normal operation of repeaters, measure the communication quality at the service
region using terminals or testers and optimize the wave environment while comparing it
with the status before opening by seeing if there is no wave shade region or
communication impossibility region.

9.2 Troubles and Checkup
9.2.1 Repeater Checkup
When checking repeaters periodically or due to abnormality in service, check the existence of
abnormality in the equipment according to the following sequence.
(１) Confirm the RF input/output level of repeaters on NMS, LED of repeaters, etc. using
GUI, measure communication quality using terminals or testers in case of regular
inspection, and follow the following procedures even though the RF input/output level of
repeaters on NMS is normal when abnormality takes place in service.
(２) Check the output status by connecting a wave analyzer to the test terminal of repeaters.
(３) Check the output values using the coupling port.
(４) Check if the repeater output value confirmed by a waveform analyzer coincides with the
actual repeater output value.
(５) If the output value measured by a waveform analyzer does not coincide with the actual
setting value, check the repeater input level.
(６) If the input level is not equal to the previous setting and there is a remarkable difference
in the input level, check the antenna attachment status and the feeder cable installation
status.
(７) If there is abnormality in the repeater output value by comparing the input level with the
repeater operation gain, turn on/off the repeater power switch, confirm the output status
with a waveform analyzer again, and if it is a severe trouble, replace it with a spare part
so that there may be no trouble in providing normal service.
9.2.2 Facility Checkup
Parts and items to be check during regular checkup or during occurrence of abnormality in
service are as follows.
iDEN
Checkup parts Checkup items Remarks
Donor antenna and service
antenna
Check if there is no abnormality in the antenna
attachment status and if the received signal
intensity of donor antenna and the RSSI value
are good.
