Abstract
A reconfigurable radio frequency circuit is arranged for receiving at least one carrier in a wireless communications terminal arranged to receive at least two carriers, each of the two carriers being transmitted in a different one of a plurality of operating frequency bands, and each of the plurality of operating frequency bands occupying a part of a first or a second frequency range. The circuit includes a combiner for connecting the output of a first receiver filter at a first operating frequency band within the first frequency range to the input of an amplifier and for connecting the output of a second receiver filter at a second operating frequency band within the second frequency range to the input of the amplifier. The amplifier has a selectable operating frequency range, the operating frequency range being selectable at least between the first frequency range and the second frequency range.
