1. A radio frequency switch comprising:

  • a first transmission line;

    a second transmission line;

    a first electrode electrically coupled to the first transmission line;

    a second electrode electrically coupled to the second transmission line; and

    a phase change material, the first transmission line coupled to a first area of the phase change material and the second transmission line coupled to a second area of the phase change material;

    wherein when a direct current is sent from the first electrode to the second electrode through the phase change material, the phase change material changes state from a high resistance state to a low resistance state allowing transmission from the first transmission line to the second transmission line; and

    wherein the radio frequency switch is integrated on a substrate.
