System and Method for Dynamic Impedance Tuning to Minimize Return Loss

A method for tuning impedance at a node, comprising:

• determining a first impedance associated with a first component when the first component is operating;
• determining a second impedance associated with the first component when the first component is not operating;
• determining a third impedance associated with a second component when the second component is operating, wherein the second component is coupled to the first component at a node;
• determining a fourth impedance associated with the second component when the second component is not operating;
• tuning an impedance at the node based at least in part upon a plurality of the first impedance, the second impedance, the third impedance, and the fourth impedance.

A method for minimizing return loss, comprising:

• determining a plurality of first impedances, each first impedance associated with a corresponding one of a plurality of components when the component is operating, wherein the components are coupled to each other at a node;
• determining a plurality of second impedances, each second impedance associated with a corresponding one of the plurality of components when the component is not operating;
• and
• tuning an impedance at the node based upon at least some of the first impedances and at least some of the second impedances.
