Document Type and Number:
WIPO Patent Application WO/2021/143193
Kind Code:
A1
Abstract:
Disclosed are a power control apparatus and method, and a storage medium. The power control apparatus comprises: a controller for determining, when a frequency band selection instruction is detected, a target frequency band from the frequency band selection instruction in response to the frequency band selection instruction, and determining, on the basis of the target frequency band, a target interstage matching circuit of a passage from among a plurality of interstage matching circuits; a driving device for pre-amplifying, when an input power signal within the target frequency band is received, the input power signal to obtain a pre-amplified power signal and transmitting same to the target interstage matching circuit; the target interstage matching circuit for processing the pre-amplified power signal to obtain an intermediate input signal and providing the intermediate input signal to a power stage amplification circuit; and the power stage amplification circuit for amplifying the intermediate input signal to obtain an output power signal.
