Abstract
The invention provides a switched linear amplifier for amplifying an input signal for provision to a communication medium. The switched linear amplifier includes a linear amplifier, an output current detector, and a switched inductive circuit. The linear amplifier amplifies the input signal to produce a linearly amplified signal. The output current detector is operative to detect an output current level having a magnitude greater than a predetermined threshold and provide a control signal. The switched inductive circuit is responsive to the control signal from the output current detector to provide an output current via a switched (and ideally lossless) inductive path, to provide a highly efficient means of generating a linearly amplified signal for provision to the communication medium.
