SYSTEM CONFIGURATION ................................................................................
FCC ID : U88GSTR1937DT-SPR 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.
FCC ID : U88GSTR1937DT-SPR 2. 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.

FCC ID : U88GSTR1937DT-SPR 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.
