An adjustable threshold power limiter circuit. A number of switching elements are included with at least a first and second switching element that each has a first terminal, a second terminal, and an insulated gate terminal. The switching elements forming a conductive path between its first and second terminals based on a voltage between its insulated gate terminal and one of its first or terminal exceeding a threshold. A conductive path is present with a series connection of the switching elements between a signal input and a reference potential. A controller is included and is electrically coupled to each insulated gate terminal of each switching element to independently provide to each insulated gate terminal either an on voltage or an off voltage.
