FILTER CIRCUIT, FILTER AND MANUFACTURING METHOD THEREFOR, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2024/020768

A1

The present disclosure relates to the technical field of communications, and provides a filter circuit, a filter and a manufacturing method therefor, and an electronic device. The filter circuit of the present disclosure comprises 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 connected in series with the impedance matching network, respectively; the first resonant sub-circuit is configured to allow a signal of which the frequency is higher than a first frequency to pass through; the second resonant sub-circuit is configured to allow a signal of which the frequency is lower than a second frequency to pass through, the second frequency being greater than the first frequency; the impedance matching network allows a signal of which the frequency falls between the first frequency and the second frequency to pass through; and the impedance matching network comprises a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, and a first inductor.
