1. A set of inductive cable baluns for a magnetic resonance imaging (MRI) radio frequency (RF) coil, the set of inductive cable baluns comprising:
a first resonant circuit and a second resonant circuit, wherein each of the first and second resonant circuits comprises an inductor;
a first decoupling circuit leg between and shared by the first and second resonant circuits, and including one or more decoupling inductors and/or one or more decoupling capacitors; and
a first cable bundle that is wound to form the inductor of the first resonant circuit or is spaced from and inductively coupled to the inductor of the first resonant circuit.
