Abstract: Methods, apparatuses, electronic devices, and readable storage mediums are provided. An example electronic device includes a first radio frequency link and a second radio frequency link. The first radio frequency link includes a component configured to detect an antenna parameter. The second radio frequency link includes a tunable component. An example method includes obtaining first antenna parameter information of the first radio frequency link by using the component that is comprised in the first radio frequency link and that is configured to detect an antenna parameter. The example method further includes tuning, based on the first antenna parameter information by using the tunable component in the second radio frequency link, an antenna corresponding to the second radio frequency link.

Abstract: A wireless communication system includes: a processing circuit, at least one linear amplification circuit, a switch amplification circuit, at least one first filter capacitor, and at least one power amplifier. An output end of the switch amplification circuit, an output end of the linear amplification circuit, and a power supply end of the power amplifier are coupled at a first node. The first filter capacitor is coupled to an input end of the linear amplification circuit or the output end of the linear amplification circuit.
