Conversion Gain using HB analysis

Maria98

hi, i am trying to simulate the conversion gain of the upconverter double balanced mixer, taking an example from one paper (schematic below). I did not understand the setting of the two tone analysis to get a 1 GHz input harmonic for the input IF port and a 60 GHz output harmonic for the modulated output port ( to get the power gain curve). Please guide for two tone setting. Thanks

  • Hi Maria,

    You can find the instructions here:

    Simulating Mixers

    You will need to scroll down a bit to get to the two-tone part...

    By the way, you can also find this mixer from the user guide under your Spectre installation:

    <SPECTRE>/tools.lnx86/spectre/examples/SpectreRF_workshop

    You can then copy the tarball to you work area, un-tar it and play... The mixer is here:

    Lib WorkshopLib, Cell db_mixer

    Some things are already pre-set in maestro_ref, but I think those are some noise tests. You will have to build two-tone tests yourself by following the guide.

     

    Good luck!
