POWER AMPLIFIER MODULES INCLUDING RELATED SYSTEMS, DEVICES, AND METHODS

Abstract:

One aspect of this disclosure is a power amplifier system that includes a control interface, a power amplifier, a passive component on a same die as the power amplifier, and a bias circuit on a different die than the power amplifier. The control interface can operate as a serial interface or as a general purpose input/output interface. The power amplifier can be controllable based at least partly on an output signal from the control interface. The bias circuit can generate a bias signal based at least partly on an indication of the electrical property of the passive component. Other embodiments of the system are provided along with related methods and components thereof.
