A module for a mobile radio device is proposed, whose central element is a
multiswitch MS, which, as desired, can connect outputs for transmission
and/or reception branches SZ, EZ of different mobile radio systems to an
antenna ANT. The module is suitable for a multiband operation and,
optionally, additional multimode operations and includes at least one
pair of outputs for transmission and reception branches of a frequency
duplexed mobile radio system. Between each output of the multiswitch and
the antenna, a matching element is provided, which allows an electrical
matching of the branches to be connected to it. The duplex operation is
carried out via separate transmission and reception filters, or on the
switch via separate outputs for transmission and reception branches.
