    Suggestion to design a matching network

    Hi, I should design a matching network that gives required different input impedances at different frequencies as in the figure.

    I found this relevant to my problem.

    I should use Transmission line based T network and see how close I can get to those required impedance values. It is related to broadband Matching.

    As someone pointed out in the previous post, I could only think of matching from 50 ohm to the needed impedance at the center frequency of the band (sqrt(Fmin*Fmax)). Anyone has better Ideas? Thanks

    When it comes to challenging matching network requirements, I really like the Optenni Lab software.

    I would use the ADS Optimizer to design a matching network over a wider band.

    An analytical method may be found but it's so hard..

    I'm not sure if thats what you want, but you can use an RF switch(SP6T or something like that) with a couple nanosec~switch time; and design different matching networks covering different frequencies.
