1.Lowest possible pass band attenuation 2.High stop band attenuation and steep filter edges 3.RoHS compliant APPLICATION 

nSince the demand for frequency bands in telecommunication keeps growing continuously the spacing between transmitting and receiving frequencies is getting narrower, which increases mutual interferences and disturbances.

nThis reduces the system power and finally results in more call interruptions such as poor video quality or increasing call interruptions. The filters have been designed for the lowest possible attenuation in the pass band. This helps minimizing the inevitable loss of useful power . In addition filters stand out for high stop band attenuation and steep filter edges.
