LNA input pad shielding
Hi all ,
I want to know why the lna input pad need to be shielded? And I don't know if in rescent RF cmos process the substrate resistivity is very small, so the substrate res from a large distance is also very small?
If the substrate resistivity is very small , is the lna input pad needed to be shielded?
