The following figure shows the RF block diagram of the Node C. 
 

 

figure 5-2 Configuration of a Node C network element 

 
The Node C is designed to amplify signals between multiple mobiles and a base 
station in a CDMA system. The unit consists of a filter and amplifier chain in the 
downlink and one or two filters and amplifier chains in the uplink (primary and 
diversity). The uplink and downlink paths are connected via a duplexer on both ends 
of each path.
