Section 1. Overview
TRI-band RF Repeater is designed for increasing coverage and capacity in Sprint’s
CDMA & iDEN systems. The repeater can provide coverage for all troubled areas such
as suburban, shadow areas, backside of mountains, urban and metropolitan locations.
The SKTS Products also provides easy installation, remote status monitoring and control
function (NMS System) through the wired line and wireless modems. SKTS’ RF
Repeater is designed to help support existing legacy equipment and help Sprint provide
nationwide service.
SK telesys improved Repeater System for Sprint CDMA band to meet the requirements
for coverage in the contiguous and non-contiguous spectrum in North America. The
digital filter manipulates discrete samples of an input signal to produce a filtered output
signal. This brand new repeater system utilizes the digital filter technology. This removes
the noise and passes the extract spectrum needed in digital signal processing systems
(DSP). The digital filter carries the filtering of sampled-data, or discrete-time, signals,
which are typically digital representations of analog signals which have been generated
by way of analog-to-digital conversion. Digital signal processing has an advantage over
analog processing in that it enables an exact reproduction of the signals and the
processing operations without any degradation in the signal.
The Tri-Band RF repeater is designed to be elastically applied to any frequency of iDEN
band, and the frequency selection level of the frequency bandwidth to service of the
Down Link and Up Link through 1 Up/Down converter module is excellent and minimizes
interference in other signals. Besides, this is designed to enable users to select their
desired band(a maximum of 20MHz) in the CDMA 65MHz band.
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 and PAU(Power Amplifier
Unit).

About Block Diagram
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. 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), differently from the down link.
And, Digital filter of the up/down converter module for CDMA converts the analog to
digital and transmits it to the FPGA in order to filter out the signal. FPGA has a logic
algorithm that can filter out each possible Bandwidth in FA, 1.25MHz, minimum value
and it selects when CPU send a command to select the pass band. Digitalized signal
goes through the DA converter after filtering the signal in any 65MHz PCS band by
digital section. Digital filter guaranties a uniform RF division output and an accurate
filtering service band in any Sprint PCS spectrum. Also it provides less spatial limitation
when designing the HW for the most complicated pass band combinations.
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.

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 restraining them to remove spurious and to improve degree of separation.
And, IF signal at the Digital filter of up/down converter module for CDMA is converted to
Digital Domain Signal by A/D Converter and sent to the FPGA. The Signal at the FPGA
will be filtered out and sent to the D/A Converter. All process of ADC, DAC and FPGA
synchronizes in the 10MHz Reference Clock TCXO in order to promise an accurate. All
process synchronizes in the 10MHz Reference Clock TCXO in order to promise an
accurate converting. All possible bandwidth combinations are 1.25, 2.50, 3.75, 5.00, 6.25,

Block Diagram for CDMA Digital Filter
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.

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.

5.1.5
PAU
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.
