CDMA REPEATER 4. System Block Diagram 4.1 Block Diagram < Fig. 7 > Block Diagram 4.2 Block Diagram description The filter as a cavity typed one is linked with Donor ANT and Service ANT of CDMA repeater, which selectively passes the broadband wanted between the received signal and terminal signal. Up/Down Converter Module consists of Down converter, Up converter and IF SAW Filter of variable bandwidth from Filter to PAU input between Down link and Up link of CDMA repeater.
CDMA REPEATER paths of 5MHz bandwidth. Each divided signal minimizes influence on other signals, removes spurious waves, and improves separation levels by taking excellent Roll Off characteristics while passing through the IF SAW and intercepting neighboring other bands and signals. PAU amplifies CDMA signal at proper output level with the module at the final end and passes by Filter to emit through ANT.
