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. S-Parameters of the TOKO 1:1 balun B5FL are available on request. 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 Jan 03, 2003 SAW Components Low Loss Filter for Mobile Communication Data Sheet Normalized transfer function passband (measured single ended - single ended) B4871 135,54MHz Normalized transfer function wideband (measured single ended - single ended) 5 Jan 03, 2003 SAW Components Low Loss Filter for Mobile Communication Data Sheet Normalized transfer function passband (measured balanced - balanced) B4871 135,54MHz Normalized transfer function wideband (measured balanced - balanced) 6 Jan 03, 2003 SAW Components Low Loss Filter for Mobile Communication Data Sheet B4871 135,54MHz Published by EPCOS AG Surface Acoustic Wave Components Division, SAW MC WT P.O.
