Important specifications include the center frequency, passband (expressed either as start and stop frequencies or as a percentage of the center frequency), rejection and steepness of rejection, and width of the rejection bands. RF Band pass filter is passive RF components used to pass signals within a specific frequency band and reject unwanted out-of-band signals, which are widely used in wireless transmitters and receivers for removing unwanted/noise signals .

Applications of the Band Pass Filter
•  Band pass filters are used in a wide range of applications such as mobile devices
•  Satellite technology uses bandpass filters to choose the desired spectrum
•  Automated vehicle technology is using bandpass filters in their transmission modules
•  Wi-Fi routers are using band pass filters to improve signal selectivity and avoid other noise from surroundings
•  High-performance Band pass filters are used in 5G supported devices to improve signal quality
•  Other common applications of bandpass filters are RF test laboratories to simulate test conditions for various applications
