Abstract
A power control device includes: a controller configured to, when a frequency band selection instruction is detected, determine a target frequency band from the frequency band selection instruction in response to the frequency band selection instruction; and to determine, based on the target frequency band, a target inter-stage matching circuit of a path from a plurality of inter-stage matching circuits; a driving element configured to, when an input power signal within the target frequency band is received, pre-amplify the input power signal to obtain a pre-amplified power signal and transmit the pre-amplified power signal to the target inter-stage matching circuit; the target inter-stage matching circuit configured to process the pre-amplified power signal to obtain an intermediate input signal and provide the intermediate input signal to a power stage amplification circuit; the power stage amplification circuit configured to amplify the intermediate input signal to obtain an output power signal.
