  • Multi-mode power amplifier
    Patent number: 8824991
    Abstract: A multi-mode power amplifier includes a high-power mode amplifier circuit, a mid-power mode amplifier circuit, and a low power amplifier circuit, where the low-power mode amplifier circuit comprises a plurality of independently selectable power cell/amplifier branches. The multi-mode power amplifiers selectively enable or disable amplifier branches to provide multiple levels of amplification. Selectively enabling certain of a plurality of split collector amplifier branches provides multiple low power and ultra-low power amplifier modes without the impedance mismatch or board layout problems associated with an RF switch.
    Type: Grant
    Filed: December 3, 2013
    Date of Patent: September 2, 2014
    Assignee: Skyworks Solutions, Inc.
    Inventors: Shiaw Wen Chang, Xuejun Chen, Guohao Zhang, Jing Sun, Piyou Zhang, Jinim Won
