    hi
    what software you are using for your simulation of filter and at what frequency is your requirement mention all those things clearly here

    Re: How to simulate the "Poly_phase Filter" ?

    Hi,

    If u intend to use vs POLYPHASE filter in order to make SSB u must take care also
    I/Q mod.

    I did it in ADS vs HB.
    general idea in my design was:
    Single ended signal was transformed in to the balanced (balun), after that u have PolyPhase Filter and after that u put IQ mod model (i don't have it so i built it also).

    David

    These are used at a low enough frequency that any SPICE type simulator can be used. If you want to be more accurate you can put a small inductor in series with the capacitor (in the simulation) to take care of SRF.
