Bandpass Filter

BRD Opticalwas founded in 2004, and is located in the city of Changchun-the optic base of China with a beautiful view and profound optical culture. We have state-of-the-art, modern technology machines for manufacturing and inspecting all kinds of precision optics. Our company occupies an area of 2,000 square meters, supported by 120 workers.

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

As the best optical bandpass filter manufacturer, we can provide ideal bandpass filterand optical bandpass filter.

Description Of Bandpass Filter

Bandpass filters are widely used in wireless transmitters and receivers. The main function of such an ideal band pass filterglass 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, bandpass filter typesallow 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, wellwaveguide bandpass filter design, 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.
