Commercial Products 5-Pole Reflectionless Bessel Low-Pass Filters PN 469582 This high performance Absorptive Low Pass Filter approximates a 5th order Bessel Thompson Filter with linear phase and low return loss extending well beyond the filter 3 dB bandwidth. It is intended to be used in high data rate communication systems requiring noise bandwidth control and linear phase. The filter is available at user defined 3 dB points with guaranteed group delay and retur n loss performance for applications up through OC-768 data rates.
