1. 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.

2. System Configuration
2.1 US PCS 1900 service organization
US PCS 1900 repeater decreases blanked and shadowed areas and extends cell coverage by re-
transmitting signal. The signal is received from BTS via Antenna directly, thus excluding
additional expenses for signal transmission (like cabling). Service organization of CDMA In-
building 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.

2.2.2 Uplink Path
FWD and RVS Gain Budgets have similar structure. 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.
<Pic.5> 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.
