The insertion attenuation of each balun is 0,6 dB at fN. The loss of the baluns is not included in the specified filter insertion attenuation. The level of ultimate suppression may be limited by electromagnetic feedthrough depending on the layout of the pcb and the arrangement of the matching components. The above mentioned characteristics can be realized either in balanced or in unbalanced mode of operation. For more details see our application note PCB Layout for Highly Selective IF Filters. 4 March 06, 2002 SAW Components Low Loss Filter for Mobile Communication Data Sheet Transfer functions passband and wideband, measured se/se on PCB B4865 134,04 MHz 5 March 06, 2002 SAW Components Low Loss Filter for Mobile Communication Data Sheet B4865 134,04 MHz Published by EPCOS AG Surface Acoustic Wave Components Division, SAW MC WT PD P.O.
