SPRINT User Manual iDEN 30dBm 4 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. 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. Abbreviation PAM: POWER AMPLIFIER MODULE LNA: LOW NOISE AMPLIFIER AGC: AUTO GAIN CONTROL ALC: AUTO LIMIT CONTROL
SPRINT User Manual iDEN 30dBm 52. SYSTEM STRUCTURE 2.1 Network structure for iDEN 30dBm 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. <Pic.1> iDEN In-building Repeater Service Organization

SPRINT User Manual iDEN 30dBm 8- 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 filters having excellent Roll off characteristics for the best optimized operation. <Pic.4> iDEN In-building RF Repeater Downlink Block Diagram 2.2.3 Uplink Path Uplink Block of iDEN In-building RF Repeater is separated as four (4) parts. - Filter part for Multiplex four (4) bands as each 800MHz and 900MHz TX/RX in Front End 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.
SPRINT User Manual iDEN 30dBm 9- Power Amplifier part for power amplifier and Level Monitoring/VSWR monitoring to adjust desirable output power of Repeater 800MHz IF Converter part is designed to select single path, and it can be minimizing signal interference between paths, and power consumption according to controls of electric power in each SAW Filter part. <Pic.5> iDEN In-building RF Repeater Uplink Block Diagram 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. 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
