SUMMARY US PCS 1900 RF repeater is an analog RF repeater, which improves PCS network. US PCS 1900 RF repeater receives RF signal from BTS and transmits it to the blanked and shadowed area, thus providing and improving voice and image data services. US PCS 1900 RF repeater’s goal is to support BTS’s functions proportionately. US PCS 1900 RF repeater communicates with BTS wirelessly, thus saving additional costs for its maintenance. US PCS 1900 RF repeater consists of PA (Downlink, Uplink), IF, LNA (Downlink, Uplink), I/O & Control divisions, which are supplied with Alarm LED, thus providing quick and easy maintenance and troubleshooting of the repeater. This manual describes in general structure of US PCS1900 repeater, its application, maintenance and troubleshooting, installation and operation etc. Abbreviation PA: Power Amplifier IF: Intermediate Frequency LNA: Low Noise Amplifier I/O: Input/Output Ethernet Instruction “ This equipment is indoor use and all the communication wirings are limited to inside of the building” or similar texts. Replaceable batteries instruction CAUTION RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECTIVE TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS For PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the equipment and shall be easily accessible.

System Configuration 2.1 US PCS 1900 service organization US PCS 1900 repeater decreases blanked and shadowed areas and extends cell coverage by retransmitting signal. The signal is received from BTS via Antenna directly, thus excluding additional expenses for signal transmission (like cabling). Service organization of CDMA Inbuilding RF repeater is shown at the picture below. Donor Antenna is directed to BTS, and being divided at Service Antennas are installed in the building and parking place. Pass Loss should be taken into consideration while dividing and cabling.US PCS 1900 Service organization 2.2 System Design and Operation 2.2.1 System design HYUNDAI CALIBRATION & CERTIFICATION TECHNOLOGIES CO., LTD.

In case of Uplink Path, RF signal is transmitted from Service Antenna to Service Cavity Filter and RVS LNA division, then the signal is transferred to IF division, where desirable Band is selected by passing 6 Paths of RF Switch and SAW filter. Selected Band is got together in FWD LNA division, and then transmitted to Donor Antenna passing through Digital ATT (10dB ATT Range) and Donor Cavity Filter. Then the signal is transmitted to BTS through Donor Antenna. Uplink Block Diagram 2.2.3 Downlink Path Downlink Path is organized in reverse order of Uplink Path. In case of Downlink Path, RF signal is transmitted from Donor Antenna to Donor Cavity Filter and FWD LNA division, then the signal is transferred to IF division, where desirable Band is selected by passing 6 Paths of RF Switch and SAW filter. Attenuation range is 40dB in Digital Attenuator. Selected Band is transmitted to FWD Drive Am and Service Cavity Filter, after that the signal is transferred to Service Antenna.
