Bandpass filters are widely used in wireless transmitters and receivers. The main function of such a filter 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. Signals at frequencies outside the band which the receiver is tuned at, can either saturate or damage the receiver.
Additionally they can create unwanted mixing products that fall in
band and interfere with the signal of interest. Wideband receivers
are particularly susceptible to such interference. 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.
This is the transmission curve of the 625-665nm narrow band pass filter:
