Abstract

A filter circuit includes a first resonant sub-circuit, a second resonant sub-circuit and an impedance matching network; the first resonant sub-circuit and the second resonant sub-circuit are each connected to the impedance matching network in series; the first resonant sub-circuit is configured to allow a signal with a frequency higher than a first frequency to pass; the second resonant sub-circuit is configured to allow a signal with a frequency lower than a second frequency to pass, and the second frequency is greater than the first frequency; the impedance matching network is configured to allow a signal between the first frequency and the second frequency to pass; the impedance matching network includes a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor and a first inductor.
