ABSTRACT:
The invention provides a system that enables a power amplifier to operate in a compressed mode and then be switched during operations to operate in a linear mode. Broadly conceptualized, the system may include a power amplifier and a bias controller that efficiently permits a communication device to function with either the compressed waveforms of a first air interface system or linear waveforms from other air interface systems.
