Figure 4.1 The block diagram of a band selective repeater 
 
Figure 4.1 shows the block diagram of a band selective repeater. This diagram is applicable to 
repeaters for CDMA systems. 
 
4.1 Downlink signal path 
 
The downlink signal path, i.e. from the base station through the repeater to the mobile station, is 
described for Mini 200 in the above block diagrams. 
 
4.2 Uplink signal path   
 
The uplink signal path, i.e. from the mobile station through the repeater to the base station, is identical 
to the downlink path but the other way round. Only some levels and component values differ.
