Hi,
I am trying to carry out an LC shunt Notch filter for 1820 MHz, BW 30 MHz and IL of around -20/30
to have it at the output of a PA to suppress some harmonics.
When I try some configurations on ADS with lumped components, looks possible, when I switch to real components with real parasitics.....it shifts a lot!
Any idea?
Perhaps I am trying a poor approach from scratch...
Thx

Try "microstrip line filter" at that frequency with a high dielectric substrate for relatively small layout and do a EM simulation to obtain this precise filter specification.
