Abstract
This application relates to the field of radio frequency technologies, and discloses a radio frequency component, an antenna system, and a base station. The radio frequency component combines a first signal and a second signal into a third signal, and splits the third signal into the first signal and the second signal. The radio frequency component is a reflectionless component, and can mitigate resonance phenomena.
