Compression control of cascode power amplifiers. A power amplifier module can include a power amplifier including a cascode transistor pair. The cascode transistor pair can include a first transistor and a second transistor. The power amplifier module can include a current comparator configured to compare a first base current of the first transistor and a second base current of the second transistor to generate a comparison signal. The power amplifier module can include a saturation controller configured to maintain the power amplifier out of saturation based on the comparison signal.
