Abstract: The present invention provides a receiver including a first band group, a second band group and a mixer. The first band group includes at least one LNA, wherein the first band group is configured to select one first LNA to receive a first input signal to generate an amplified first input signal. The second band group includes at least one LNA, wherein the second band group is configured to select one second LNA to receive a second input signal to generate an amplified second input signal. The first band group and the second band group are coupled to a first input terminal and a second input terminal of the mixer, respectively, and the mixer receives one of the amplified first input signal and the amplified second input signal to generate an output signal.

Abstract: A communication unit includes a plurality of parallel radio frequency, RF, signal paths. Located between a first RF signal path of the plurality of parallel RF signal paths comprising at least one first RF amplifier and a second signal path comprising at least one second RF amplifier is one of a shared inductor or shared transformer. The at least one first RF amplifier is coupled to a supply voltage via a first switch and at least one second RF amplifier is coupled to the supply voltage via a second switch, and the first switch is closed that provides the supply voltage to the at least one second RF amplifier whilst the second switch is opened.
