RF amplifier employing active load linearization |
摘要 |
A method and apparatus for linear amplification of a modulated carrier signal or multi-carrier signal is disclosed. The linearity of the amplifier is improved by employing dynamic load line adjustments. A second current source coupled to the amplifier output load is turned on just before the amplifier reaches a nonlinear regime and reduces the effective load to prevent the amplifier allowing sufficient power to reach the nonlinear regime near saturation. The technique is particularly advantageous for amplification of a signal with large peak to average ratio.
