Hi Folks;
I want to learn to design RF circuits. However, I can't afford a decent spectrum analyzer but 1-2Ghz range cheap ones. (Rigol, Siglent, etc...)
Is it possible to extend the frequency range of those analyzers with simple mixers? (10Ghz? 20Ghz?)
I guess that it is not possible to design an infinite bandwidth perfect matching circuit between two active devices. If so how did spectrum analyzers manufacturers solve this problem? Or what happens if there is a mismatch?
