4.2 Block Diagram description
This was realized in one body type available in both of an iDEN frequency band and a CDMA
frequency band with a filter of cavity type and has only the iDEN frequency band and CDMA
frequency band to service pass selectively after securing isolation between the Down Link and
UP Link enough while other bands are removed because, of the base station(EBTS) signals of
the iDEN and CDMA received through antenna, only the desired bands are made to pass
selectively since it is connected to the donor ANT of repeaters.
The up/down converter modules of the Tri-Band RF repeater were realized for iDEN and
CDMA respectively. The Up/Down Converter Module for iDEN is composed of a down converter
and up converter from the filter to the PAU input in the down link and up link of repeaters and a
digital filter of the variable bandwidth. Besides, the same structure is composed in a pair in order
to handle two bands such as a 900M band and a 800M band.
The up/down converter of the down link was realized as a digital filter through a conversion
and A/D conversion from the base station(EBTS) signals inputted through the LNA part to the IF
frequency (62.5MHz).
The up/down converter of the Up Link was made to take a Roll Off characteristic using a SAW
filter by converting the RF signal of the terminal inputted through the LNA into the IF
frequency(70MHz)l, differently from the down link.
And, the up/down converter module for CDMA is divided into 1 path of 20MHz bandwidth and 3
paths of 5MHz bandwidth using a SAW filter by converting the signals inputted through the LNA
into the IF frequency(140MHz).
This minimizes influence on other signals, removes spurious waves, and improves separation
levels by suppressing neighboring signals using a digital filter and SAW filter.
The signals passing through the Up/Down Converter are inputted as a PAU module for iDEN
and CDMA respectively, so as to amplify the iDEN signals and CDMA signals to a proper output
level, pass through a filter realized with an iDEN frequency band and a CDMA frequency band
in one body type, and then be discharged through ANT.

5. System Overview
5.1 Construction and Features of System
The Tri-Band RF repeater was arranged so that operators may efficiently utilize composition
modules when composing and operating the iDEN service network and the CDMA service
network jointly.
The Tri-Band RF Repeater is basically installed by wall, and if required it is constructed to be
installed on 19 inch Rack. And the earth terminal is attached to the bottom of the repeater for
earth.
The CCD of the Tri-Band RF repeater has a local repeater control function to continuously
manage and control repeaters for stable services of repeaters installed at the site and a remote
repeater control function to support remote monitoring and control using an intensive monitoring
system for repeaters.
The basic structure of a Tri-Band RF repeater is such that 1 output port is supported to 1 input
port. The inside of a repeater is divided into a block for iDEN and a block for CDMA, and the
DL(Down Link) Converter and UL(Up Link) Converter for iDEN and CDMA are composed as
one module respectively for optimum size and high efficiency. Besides, this is composed of
PSU(Power Supply Unit), Filter, controller, and PAU(Power Amplifier Unit).

Tri-Band REPEATER
5.1.1 PSU (Power Supply Unit)
With AC power input for A/D or D/D conversion it is used to supply safe direct current power to
each device equipped with active degauss, using main active degauss for industrial or
equivalent semi-conducts to satisfy every electrical features with strong nature.
Its power takes AC 108-127V input to convert to DC 3.8V, DC 7V, DC 12V and DC 27V for use.
5.1.2 Controller
The controller consists of RCB(RF Control Board) and NCB(Network Control Board) to monitor
and control the state of each module of Tri-Band repeater.
RCU(RF Control Unit) is linked to GUI through DEBUG port to collect the inspected information
of modules and control.
NCB(Network Control Board) enables upper NMS(Ethernet) communication through RJ-45 port
to inspect and control the state. It has LED to show the state in NCB(Network Control Board)’s
front to easily confirm the abnormal condition of Module.

5.1.3 Up / Down Converter
Up/Down Converter modules of the Tri-Band RF repeater were realized for iDEN and CDMA
respectively. The Up/Down Converter Module for iDEN is composed of a down converter and up
converter from the filter to the PAU input in the down link and up link of repeaters and a digital
filter of the variable bandwidth. Besides, the same structure is composed in a pair in order to
handle two bands such as a 900M band and a 800M band.
Up/Down Converter of Down Lind converts EBTS signal input through LNA part to IF
frequency(62.5MHz) and embodies Digital Filter as A/D conversion.
It takes Roll off nature with digital filter, minimized the impact of other signal by stopping nearby
other band and other signal, removes spurious and improves degree of separation.
In addition, Up link unlike Down link converts Terminal’s RF signal input through LNA to IF
frequency(70MHz) to take roll off nature of SAW Filter, minimizes the impact of other signals by
Tri-Band REPEATER
restraining them to remove spurious and to improve degree of separation.
And, up/down converter module for CDMA is divided into 1 path of 20MHz bandwidth and 3
paths of 5MHz bandwidth by converting the base station(BTS) signals inputted through the LNA
part into the IF frequency(140MHz).
Each divided signal minimizes influence on other signals, removes spurious waves, and
improves separation levels by taking excellent Roll Off characteristics while passing through the
IF SAW filter and intercepting neighboring other bands and other signals.
Up/Down Converter module for iDEN and CDMA suppresses leakage of local signals into the
input terminal by inserting a band path filter on the front side of a mixer. The mixer minimizes
IMD components of the system by applying elements having characteristics of high IP3 and
minimizes influence on the next step by maintaining linearity. The base station(EBTS) signals
converted into the IF frequency are recovered into the original frequency through the up
converter.
Local stage 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.
RF Block of Down Link Up/Down Converter as Down Link Gain Control Block phase performs
AGC and ALC functions to protect devices on over-input of iDEN RF Repeater, and with the
need of user it may turn On/Off the functions with automatic compensation function for gains on
temperature of system.
5.1.4 Filter
This was realized in one body type available in both of an iDEN frequency band and a CDMA
frequency band with a filter of cavity type and has only the iDEN frequency band and CDMA
frequency band to service inputted to the LNA part after securing isolation between the Down
Link and UP Link enough while other bands are removed because, of the base station(EBTS)
signals of the iDEN and CDMA received through antenna, only the desired bands are made to
pass selectively since it is connected to the donor ANT of repeaters. Beside, the backward
direction(Up Link) minimizes the power of spurious wave discharge generated from PAU.
Tri-Band REPEATER
5.1.5 PAU(Power Amplifier Unit)
PAU considers Spurious features to apply degauss with credibility, endurance and high P1dB
and inspects at all times output by linking to system’s control part. So when main problem
happens, it can be reported to upper level and if required by the user PAU move can be On/Off.
The PAU of the Tri-Band repeater is divided into ones for iDEN and CDMA, but the PAU for
iDEN service is composed of the integrated modules of iDEN 800/900, and the PAU for CDMA
service is composed of a single module.
Down Link PAU amplifies iDEN signal and CDMA signal to proper output level and supply
Controller with VSWR information of output port and Repeater’s output level.
Also detect its own temperature and supply Controller with Device failure to check normal
operation state of Module.
5.1.6 Isolation Check Module
For the isolation check module for CDMA, the Down Link converter of the UP/DOWN converter
module is coupled to become an input of the isolation check module. Such signals find the
maximum value and minimum value by measuring a oscillation detection value while moving by
50KHz from -250KHz to +250KHz of oscillation check frequency within the module.
When the difference between the maximum value and minimum value is 2dB greater than the
setting value, the gain is compensated as much as the difference, and when it is -2dB less than
the setting value, the gain is compensated as much as -0.5dB. Isolation is monitored and
controlled through such action.
The isolation check module for iDEN find the maximum value and minimum value by measuring
the oscillation detection value while moving by 30KHz up to 798 ~ 799MHz of oscillation check
frequency through channel scanning within a module.
When the difference between the maximum value and minimum value is 2dB greater than the
setting value, the gain is compensated as much as the difference, and when it is -2dB less than
the setting value, the gain is compensated as much as -0.5dB. Isolation is monitored and
controlled through such action.
Tri-Band REPEATER
5.1.7 Cabinet
