Patent ID: 8920410

Claim:
An electrosurgical system, comprising: a power source configured to generate microwave energy; a microwave applicator configured to deliver microwave energy from the power source to tissue; a switching mechanism including a housing having input and output ports, the input port connectable to the power source and the output port connectable to the microwave applicator, the housing configured to house at least one switch therein, wherein the at least one switch is one of an absorptive/reflector pin diode attenuator or a digital programmable step attenuator; and a controller in operative communication with the switching mechanism to toggle the at least one switch from a first state, wherein the at least one switch directs microwave energy generated by the power source to the microwave applicator to a second state, wherein the at least one switch directs microwave energy to a resistive load operably coupled to the switching mechanism.
