COMBINERS
Combiners are needed to enable more than one transmitter to be
connected to one common transmitting antenna. Without a
combiner the output from one transmitter would loop back into
the output of another since both of them are physically
connected to the same antenna.
In GSM, two different TX-combiners can be used: filter and
hybrid.
