Impedance matching networks using lumped elements using FEKO

Hi,

I am a new user of FEKO. At present, I am doing two-port impedance matching network designs for a power amplifier in ADS based on lumped elements. The input signal frequency can vary from 20 MHz to 200 MHz. Is it possible to do lumped element based impedance matching network in FEKO where one of the ports has complex impedance?

Thanks in advance.

Hello @waseq81

Yes you can use either lumped elements or a general network block for impedance matching circuit, the latter might be easier depending on what you can export from ADS. For example, you can reference a touchstone file using a general network block.

Hi @Peter Futter ,

Thanks for the reply. Could you kindly let me know whether I can design the lumped element-based matching network in FEKO instead of ADS or exporting the design from ADS to work in FEKO is the only option?

Thanks in advance.

Hi @waseq81

FEKO doesn't have any direct tools for designing matching networks - you could write a script to do it, or you could use the FEKO optimiser.

The best solution would be to use Optenni Lab (https://www.optenni.com), which is available through the Altair partner alliance. The integration with FEKO is seamless and works very well / intuitively. Optenni also has tones of additional features for matching that can be really useful - tolerance analysis, component libraries, etc.
