  • Method to make RF switches and circuits with phase-change materials
    Patent number: 9293699
    Abstract: A radio frequency switch includes 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. 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. The radio frequency switch is integrated on a substrate.
