Patent ID: 8660603

Claim:
A module for mobile radio device, the module comprising: a multiswitch configured to connect outputs of the multiswitch for transmission and reception branches of different mobile radio systems to an antenna so that the module comprises transmission and reception branches of at least two mobile radio systems duplexed in the FDD mode, wherein the multiswitch allows synchronous operation of the module in a first mobile radio system and a second mobile radio system, wherein the first system is a FDD system and the second system is different from the first system; a first output of the multiswitch for connection of the transmission branch of the first mobile radio system duplexed in an FDD mode; a second output of the multiswitch for connection of the reception branch of the first mobile radio system, the second output being separate from the first output; a third output of the multiswitch for connection of the transmission branch of the second mobile radio system that is different from the first one; and a fourth output of the multiswitch for connection of the reception branch of the second mobile radio system, a fifth output of the multiswitch for connection of the transmission branch of a third mobile radio system that is different from the first and the second mobile radio systems, and a sixth output of the multiswitch for connection of the reception branch of the third mobile radio system, wherein the multiswitch comprises three of the above outputs on a first side of a switch that assigned to a transmission side and three other output on a second side of the switch that are assigned to a reception side of a respective frequency duplex mobile radio system each for connecting the respective branch to the respective output, wherein the switch is configured to provide only those switch positions that allow the simultaneous connection of corresponding pair of outputs to the antenna to allow simultaneous transmission and reception, wherein the part of the multiswitch with the antenna output and the three pairs of transmission and reception branches of the FDD duplexing mobile radio system is designed as a so-called three-on-three switch, wherein matching elements are integrated in the module to ensure FDD duplex operation for filters arranged in the transmission branch and reception branch of the first mobile radio system and are connected in this switch position to corresponding branches, wherein the matching elements are integrated in the module for each branch that can be connected to the outputs, wherein the matching elements comprise phase lines, inductances, capacitances, impedance matching networks or impedance transformation elements, and wherein a switch position is provided, in the multiswitch, wherein the switch position connects the transmission and reception branches of the first mobile radio system, as well as at least one transmission branch or reception branch of an additional mobile radio system to the antenna, so that a multiplex operation is possible via the integrated matching elements.
