Abstract:
A multi-stage radio frequency (RF) power amplifier includes a high-power amplifier path and a low-power amplifier path. The low-power amplifier path includes gain synchronization circuitry in order to synchronize the gain response of the high-power amplifier path and the low-power amplifier path. By synchronizing the gain response of the high-power amplifier path and the low-power amplifier path, the gain linearity of the multi-stage RF amplifier is improved.
