(57) [Abstract] The present invention provides a system capacity and geographical coverage increased to a mobile / portable radio transceiver using the radio communication frequency band separated and typically adjacent. Radio that transmits and receives in the frequency band of exactly one, is adapted to communicate in a frequency band extended, to include a configurable dual system. Redundant circuitry is connected between the receiver and the radio transmitter and radio antenna. For that, depending on the operating mode of the wireless transceiver, to allow communication in the transmission / reception frequency band of the set of the first or second plurality of switches is selected to configure the various transmitter antenna, redundant circuitry, and a receiver, I work basis. In the embodiment as one preferred example, only a single Deyupurekusa is employed, it is connected to the transceiver circuit and the antenna via a plurality of switches.
