FILTER, INTEGRATED PASSIVE DEVICE, ELECTRONIC DEVICE, AND DISPLAY APPARATUS

WIPO Patent Application WO/2024/082296

A1

Provided in the embodiments of the present disclosure are a filter, an integrated passive device, an electronic device, and a display apparatus. The filter, which is applied to the field of radio frequency, comprises: a first port, a second port, a first band-stop filter circuit, a low-pass filter circuit, a band-pass filter circuit and a high-pass filter circuit, wherein the first band-stop filter circuit is coupled to the first port, and is configured to perform out-of-band rejection processing on signals which are input from the first port and then input the signals into the low-pass filter circuit; the low-pass filter circuit is configured to input into the band-pass filter circuit first signals having a frequency between a first frequency and a second frequency among the signals which are input from the first band-stop filter circuit; the band-pass filter circuit is configured to input into the high-pass filter circuit second signals having a frequency between a third frequency and a fourth frequency among the first signals which are input from the low-pass filter circuit; and the high-pass filter circuit is configured to pass a third signal having a frequency not less than the first frequency among the second signals which are input from the band-pass filter circuit.
