    Hi all,
    I intend to use a bandpass filter that could operate at 433MHz. Could any body suggest what could be the possible values of the components. I have found out this online bandpass filter calculator....but I actually dont know what RL and Q are doing there.....this is the link to that calculator...
    please help me find the right value for the bandpass filter.

    Thanks
    Regards

    Diwakar

    Hello. RL stands for load resistance, which is the resistance of whatever you're hooking to the output of the filter. The calculator defines Q = frequency / bandwidth, both of which you should already know.
