iDEN repeater is located in blanket / shadow area of insider of building to transmit
iDEN800MHz, iDEN900MHz BTS signal simultaneously.
There are two types of RF Repeater for iDEN band as each 15dBm, and 25dBm output power
in system 65dB Gain, and 30dBm output power in system 80dB Gain.
This User Manual is the Repeater having 65dBGain / +25dBm output power.
Bandwidth
Downlink 851MHz~869MHz, Uplink 806MHz~824MHz (18MHz Band)
Downlink 862MHz~869MHz, Uplink 817MHz~824MHz (7MHz Band)
To avoid paging signal interference at 940MHz side, IF Converter shift SAW filter edge by
200KHz, 400KHz. (TX Edge only, not whole bandwidth).
Also, This Repeater is equipped for Output power control by AGC/ALC, Gain Control by
Attenuator adjustment, Remote Control by using Web UI and Remote Firmware Up-grade.

2. SYSTEM STRUCTURE
2.1 Network structure for iDEN 25dBm RF Repeater
Below picture shows a Network structure for iDEN In-building RF Repeater in a real site. Donor
ANT takes a position on the direction to BTS which be linked, and Server ANT is available to be
located in designated area for service by using RF cable deployments and dividers as blow.
One thing that we consider is Path losses between Repeater port and ANT in case of dividing by
dividers and RF cables. They should be equally managed.

2.2.2 Downlink Path
There are four (4) parts of downlink Block in iDEN In-building RF Repeater.
Filter part for Multiplex four (4) bands as each 800MHz and 900MHz TX/RX in Front End
of Donor/Server
LNA part of Donor/Service path to process signals of 800MHz and 900MHz bands.
7/26
FCC ID : U88GSTR-825DC-SPR
If Converter part having several bands of SAW Filter paths to adjust Band Edge of high
frequency as 200KHz and 400KHz each. In case of 800MHz band, extra Switching Filters
equipped to individually select 18MHz and 7MHz
Power Amplifier part for power amplifier and Level

adjust desirable output power of Repeater
Downlink frequency contains lots of signals such as Paging signal, DCS etc through Donor ANT.
So Out band signals should be minimized by SAW filters having excellent Roll off characteristics
for the best optimized operation.

2.2.4 Adjustable Band Edge functional circuit configuration
In case of IDEN using the bandwidth of 800MHz and 900MHz, many of Out of Band Signals is
input via Donor ANT Outdoor. The most worried signal among them is Paging Signal.
9/26
FCC ID : U88GSTR-825DC-SPR
Commercial Paging Signal of 929MHz~932MHz, 940MHz~941MHz, having the strength of Max.
-15dBm, is to be inputted into Donor ANT. Among this two kind of Paging Signal Band,
929MHz~932MHz bandwidth is possible for sufficient Rejection via SAW Filter, But
940MHz~941MHz is difficult to gain big decreasing volume even if use SAW Filter because Band
Edge is as close as to be folded to 935MHz~940MHz of being the frequency of iDEN900MHz
Downlink.
To prepare for this environment, Down Link of iDEN Repeater is designed to have additional
Roll Off characteristic by decreasing band of SAW Filter in the station adjacent to paging signal,
for it having the function of Adjust Band Edge that can decrease c of high frequency by 200 kHz,
400 kHz each.
 Additional Roll off through Adjust Band Edge
