1. A control device for a radio frequency power amplifier, coupled to a radio frequency power amplification module of the radio frequency power amplifier via a signal connection, the control device comprising:
an input signal processing module, configured to obtain, based on an input signal, a first signal for generating a control signal and a second signal for signal amplification;
a signal processing and control module configured to obtain the control signal based on the first signal;
an adjustment module configured to adjust the second signal based on the control signal; and
a delay module configured to delay a transmission of the second signal to the adjustment module, wherein
the signal processing and control module is further configured to impose an adjustable delay on the control signal to adjust a moment that the control signal reaches the adjustment module.
