Figure 4.1 Block Diagram of Band Selective Repeater
Figure 4.1 shows a 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 30 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.
