DYNAMIC RANGE IMPROVEMENTS OF LOAD MODULATED AMPLIFIERS |
摘要 |
<p>The present invention relates to methods and devices to control and operate the functionality of a power amplifier system (100) capable of operating in at least three differential amplification modes. The drive signal's amplitude envelope controls an integrated switch network (104; 105, 106) that routes both the signal envelope and signal phase to different modulation blocks (111, 112: 109, 110: 115). Depending on the envelope strength, the operational mode of the amplifier system is possible to alter to best serve the signal statistics to provide the highest overall power efficiency.</p> |
