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.
Claims20
A dual mode power amplifier system, comprising:
- an amplifier;
- and
- a bias controller coupled in signal communication to the amplifier and configured to permit the amplifier to operate in a compressed data transmission mode and in a linear data transmission mode.
A dual mode power amplifier system, comprising:
- an amplifier configured to amplify an input signal to produce an output signal;
- and
- a bias controller coupled in signal communication to amplifier, the bias controller having a means for biasing the amplifier to operate in a compressed data transmission mode and in a linear data transmission mode.
A process, comprising:
- presenting a bias controller coupled in signal communication to an amplifier;
- receiving a first input signal at the amplifier;
- moving a switch in a bias controller from a first position to a second position, where the first position represents one of a compressed data transmission mode and a linear data transmission mode and the second position represents the other of the compressed data transmission mode and the linear data transmission mode;
- receiving a second input signal at the amplifier from the bias controller;
- and
- communicating the first input signal through the amplifier as a function of the second input signal.
