NOTE: This equipment has been tested and found to comply with the li mits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will be required to correct the interference
at his own expense.
CAUTION
Changes or modifications not expressly approved
by the manufacturer responsible for compliance
could void the user's authority to operate the equipment

1. SUMMARY
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.
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 Monitoring/VSWR monitoring to
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 f ilters having excellent Roll off characteristics
for the best optimized operation.
