Abstract: Systems and methods for RF hazard protection are provided. In one embodiment, a RF protection coupler comprises: a first port to couple to an output of an RF source circuit; a second port to couple to an external RF load; a source side and load side RF switches, wherein the source side RF switch and the load side RF switch are each switch between a first and second states in response to a detected matting. In the first state the source and load side RF switches establish an electrical path between the first and second ports. In the second state: the source side RF switch couples the first port to an impedance load that is impedance matched to the output of the RF source circuit; the load side RF switch couples the second port to an electrical ground; and a gap between the switches electrically isolates the ports.
