Abstract
Embodiments of the present disclosure provide a filter, an integrated passive device, an electronic device, and a display apparatus. The filter is applied in the field of radio frequency and includes: 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. The first band-stop filter circuit is coupled to the first port, and is configured to perform out-of-band suppression on a signal input from the first port and input a signal subjected to the out-of-band suppression to the low-pass filter circuit. The low-pass filter circuit is configured to input a first signal, a frequency of which is between a first frequency and a second frequency, of the signal input by the first band-stop filter circuit to the band-pass filter circuit.
