Passive notch filter, calculated for 1.2 GHz using RF and Microwave Toolbox.  Results here in 1.42 GHz!  Thanks to hurz for the feedback.

Using “RF and Microwave Toolbox“ results in 1.4GHz which makes 200MHz difference, looks like you can waste them all

In toolbox, pick band stop filter, butterworth, fs1 = 1GHz, fs2 = 2 GHz, ripple = 3 dB, fs = 1.2 GHz, Zo = 50, N = 4. Then calculate, round off, plug into every circuit, and here's what you get :)

Let's try it in multisim, and hspice... In reality, tuning is the issue, but this is for fun. Order N = 3 uses identical caps and inductors, BTW.

BTW, of course, you're correct, hurz. The title must be corrected.
