2.1.1 Major blocks diagram
Components of repeater
The equipment consists of duplexers, uplink filters, downlink filters,
uplink band selective amplifying module, downlink band selective
amplifying module, monitoring elements and power elements.
2.1.2 Theory of Operation
The downlink signal received by the donor antenna of the base station
shall be sent to a band selective filter via duplexer to be filtered and to
be amplified by the downlink band selective amplifier to a proper level.
The coverage antenna via a duplexer shall emit the downlink signal.
Similarly, for uplink, the signal received by the re-transmission antenna
shall have its level adjusted to a regulated level by a uplink band
selective amplifier after it is filtered. The donor antenna will emit it after
it is filtered and sent to the duplexer.
