5.10 Power and Grounds
The AMIS-53050 has four distinct supply voltage inputs and two different ground nodes, respectively. This allows the separation of the
RF, analog and digital power supply circuits to reduced coupled noise in these circuits.. The same principle applies to the ground
nodes, where a separate ground plane can reduce the amount of noise induced into the sensitive RF circuits.
