Abstract

Provided are a radio frequency (RF) system, an impedance tuning method, and an electronic device. The RF system includes a first RF path, a second RF path, a first power detector, and a processor. The first RF path includes a first coupler and a first antenna radiator. The second RF path includes a second antenna radiator. The first power detector is electrically connected with the first coupler, and used to obtain, through the first coupler, a first coupled power received by the first antenna radiator from the second antenna radiator when the second antenna radiator transmits an antenna signal. The processor is configured to obtain a first voltage standing wave ratio (VSWR) based on the first coupled power, and generate, when the first VSWR is outside a preset VSWR range, a first impedance adjustment instruction used to make the first VSWR fall within the preset VSWR range. It enables tuning for antenna impedance matching.
