  • Directly heated RF phase change switch
    Patent number: 9419213
    Abstract: An RF switch is provided with a direct heating method. The RF switch is comprised of two RF electrodes disposed on opposing sides of a phase change element. Depending on the state of the phase change material, the RF electrodes form a conductive path through the phase change material for an RF signal. To control the state of the phase change material, the RF switch further includes a heater formed from two heater electrodes. The two heater electrodes are configured to draw a current through the phase change element in a direction transverse to the conductive path.
    Type: Grant
