Abstract
A control circuit and a method for controlling an operation of a power amplifier core are provided. The power amplifier core is switchable between an envelope tracking operation mode and a non-envelope tracking operation mode. The control circuit is configured to provide a control signal for controlling the operation of the power amplifier core or to process an amplified signal received from the power amplifier core in dependence on the operation mode of the power amplifier core.
