FCC ID : U88GSTR-825DC-SPR 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.
FCC ID : U88GSTR-825DC-SPR 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.

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.
FCC ID : U88GSTR-825DC-SPR of Donor/Server - LNA Part of two(2) paths for processing 800MHz and 900MHz signals - 800MHz IF Converter part and 900MHz IF Converter part of 5MHz band having Switching filter parts for selecting each 18MHz and 7MHz.
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.
