Zusammenfassung:	Embodiments of this application provide a signal processing method and apparatus, and relate to the communications field. In this apparatus, an isolation port of a 90° directional coupler is connected to a broadband impedance matching network, to provide an adjustable equivalent impedance part between input ports of the 90° directional coupler, so as to effectively improve efficiency of a back-off region of the signal processing apparatus.
