  • Transformer or inductor sharing in a radio frequency amplifier and method therefor
    Patent number: 10680560
    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.
    Type: Grant
