RECONFIGURABLE POWER AMPLIFIER AND USE OF SUCH AMPLIFIER FOR MAKING A MULTISTANDARD AMPLIFICATION STAGE FOR MOBILE PHONE COMMUNICATIONS

摘要

The reconfigurable power amplifier of the present invention includes at least one amplification circuit (E1, E2) and control means (6) of said amplification circuit for adapting the operation thereof depending on an input signal (RF in) applied thereto. The control means include means (4, 5) for modifying the compression point of said amplification circuit and for adapting the gain of the circuit in order to increase the efficient added power of the circuit for the modified compression point.
