Method and assembly for providing impedance matching network and network assembly

A plasma processing system comprising:

• a high power, radio frequency matching network including a match network component including one or more variable inductive elements including a magnetic core, a helical coil, and an actuator configured to physically translate the magnetic core through the helical coil.

A high power, radio frequency matching network assembly for a plasma processing system, the matching network assembly comprising:

• a plurality of variable inductive elements each including a magnetic core, a helical coil, and an actuator configured to physically translate the magnetic core through the helical coil;
• and
• a housing including the plurality of variable inductive elements, the housing including a housing compartment partition that shields each of the variable inductive elements from fields generated by the other of the variable inductive elements.
