The insertion attenuation of a balun is 0.6 dB at 183.6 MHz. The loss of the balun 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.
