  • Patent number: 11942902
    Abstract: Methods related to power amplification systems with adjustable common base bias. A method of implementing a power amplification system can include providing a cascode amplifier coupled to a radio-frequency input signal and coupled to a radio-frequency output. The method can further include providing a biasing component configured to apply one or more biasing signals to the cascode amplifier, the biasing component including a bias controller and one or more bias components. Each respective bias component may be coupled to a respective bias transistor.
    Type: Grant

  • Patent number: 9698734
    Abstract: Power amplification system with adjustable common base bias. A power amplification system can include a first transistor having a base coupled to a radio-frequency input. The power amplification can further include a second transistor having an emitter coupled to a collector of the first transistor and having a collector coupled to a radio-frequency output. The power amplification system can include a biasing component configured to apply a fixed biasing signal to the base of the first transistor and to apply an adjustable biasing signal to the base of the second transistor.
