Abstract
A transceiver for use in wireless communications including a first antenna and first filter coupled thereto to transmit signals in a first frequency range and a second antenna and second filter means coupled thereto to receive signals in the first frequency range or a second different frequency, in dependence on a mode of operation of the transceiver. In a first mode of operation the transceiver is arranged to transmit signals in the first frequency range via the first antenna and to receive signals in the second frequency range via the second antenna, and in a second mode of operation, the transceiver is arranged to receive signals in the first frequency range via the second antenna. Alternatively, the second antenna and second filter may receive signals in a third frequency range and in the second mode of operation, the transceiver is arranged to receive signals in the third frequency range via the second antenna.
