Abstract
Embodiments of the present disclosure provide a filter, an integrated passive device, an electronic device and a display device. The filter includes: a first port, a second port, a first band-pass filter circuit, a second band-pass filter circuit and a third band-pass filter circuit. The first band-pass filter circuit is configured to output a first signal after suppressing a signal with a frequency between a first frequency and a second frequency in an initial signal input from the first port; the second band-pass filter circuit is configured to receive the first signal and output a second signal with a frequency between a third frequency and a fourth frequency in the first signal; the third band-pass filter circuit is configured to receive the second signal and output a third signal with a frequency between a fifth frequency and a sixth frequency in the second signal to the second port.
