Abstract:
An apparatus for amplifying a telecommunication signal, comprising:an input transmission line configured to receive the telecommunication signal; an output transmission line configured to provide an amplified output of the telecommunication signal received at said input transmission line; a distributed amplifier comprising: N amplifier sections having a transistor connected to said input transmission line and said output transmission line; a waveform controller connected to said transistor of at least one of said N amplifier sections and configured to identify a signal level of the telecommunication signal, said waveform controller further configured to generate an independent biasing voltage for active operation and non-active operation of said transistor of said at least one of said N amplifier sections, wherein said waveform controller is configured to generate said independent biasing voltage such that said at least one of said N amplifier sections is configured for active operation and non-active operation based at least in part upon an evaluation of said signal level and an output power of the apparatus is reduced without a substantial degradation in an efficiency of the apparatus.
