Abstract
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.
