    Hi,
    i have to design a passive filter in place of the box in figure below

    the purpose of this filter is to maximize current at 4,45Khz and 5,52 Khz (about 10amps) on L3.
    On L3 could be the desired frequency with a positive/negative tolerance of 10Hz
    Below the graph of impdance vs freq of the desired filter

    Does anyone have any idea on this, or advice for me?

    This is just a suggestion, you can experience
    1- maximize current = series LC resonance circuit
    2- Calculate Xc3
    3- XL = Xc3 ===> calculate L
    4- Calculate XL3
    5- XC = XL3 ====> Calculate C
    6- put those LC in series instead of the box

    Search in Google Book "RF Circuit Design- Chris Bowick" it is FREE
    goodluck
