  • Output array for RF performance improvement
    Patent number: 12401381
    Abstract: A power amplifier output stage includes a first output array group having a first plurality of semiconductor devices, and a first loading adjustment module coupled to the first output array group. The first loading adjustment module is configured to adjust a loading of the first output array group to produce a first power dissipation value associated with the first output array group. The power amplifier output stage further includes a second output array group having a second plurality of semiconductor devices, and a second source loading adjustment module coupled to a second input of the second output array. The second source loading adjustment module is configured to adjust a source loading of the second output array group to produce a second power dissipation value associated with the second output array group, the first power dissipation value being different from the second power dissipation value.
