Hi,
Is it possible to use Lump components (such as pi or L network) to design a impedance match network in two different frequencies? Any recommendations tutorial or articles?

Thanks in advance
 

It is possible. You will need more elements. Now you have twice as many data points to fit.
 

You can design two bandpass filter and then cascode them together and finetune.

Yibin.
 

You certainly can, but you must understand the consequences of Foster's reactance theory.
