Title:
OUTPUT ARRAY FOR RF PERFORMANCE IMPROVEMENT
Document Type and Number:
WIPO Patent Application WO/2020/264541
Kind Code:
A3
Abstract:
A power amplifier output stage includes a first output array group (304A) having a first plurality of semiconductor devices, and a first loading adjustment module (308A) coupled to the first output array group (304A). The first loading adjustment module (308A) is configured to adjust a loading of the first output array group (304A) to produce a first power dissipation value. The power amplifier output stage further includes a second output array group (304B) having a second plurality of semiconductor devices, and a second source loading adjustment module (308B) coupled to the second output array group (304B). The second source loading adjustment module (308B) is configured to adjust a source loading of the second output array group (304B) to produce a second power dissipation value, the first power dissipation value being different from the second power dissipation value.
