1. A method of implementing a power amplification system, the method comprising:
providing a cascode amplifier coupled to an input and an output; and
providing a biasing component including one or more sensors for detecting at least one of a temperature or a power condition of the power amplification system, the 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 coupled to a respective bias transistor.
