Bandpass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range.

 As one of the best optical bandpass filter manufacturers, we can provide ideal bandpass filters.

 Description Of Bandpass Filter

Bandpass filters are widely used in wireless transmitters and receivers. The main function of such an optical filter glass in a transmitter is to limit the bandwidth of the output signal to the band allocated for the transmission. This prevents the transmitter from interfering with other stations. In a receiver, a bandpass filter allows signals within a selected range of frequencies to be heard or decoded, while preventing signals at unwanted frequencies from getting through. A bandpass filter also optimizes the signal-to-noise ratio and sensitivity of a receiver.

 In both transmitting and receiving applications, well-designed bandpass filters, having the optimum bandwidth for the mode and speed of communication being used, maximize the number of signal transmitters that can exist in a system, while minimizing the interference or competition among signals.
