Abstract
A frequency selective limiter (FSL) is provided having a transmission line structure with a tapered width. The FSL includes a magnetic material having first and second opposing surfaces. A first conductor is disposed on the first surface of the magnetic material, where a width of the first conductor decreases from a first end of the FSL to a second end of the FSL along a length of the FSL. Two second conductors are disposed on the second surface of the magnetic material, where a width of a gap between the two second conductors decreases from the first end of the FSL to the second end of the FSL along a length of the FSL. The first conductor and two second conductors form a biplanar waveguide transmission line.

A frequency selective limiter (FSL) comprising:
- a first magnetic material having first and second opposing surfaces;
- a first conductor disposed on the first surface of the first magnetic material, a width of the first conductor decreasing from a first end of the FSL to a second end of the FSL along a length of the FSL;
- and
- two second conductors disposed on the second surface of the first magnetic material, a width of a gap between the two second conductors decreasing from the first end of the FSL to the second end of the FSL along a length of the FSL.
A cascaded frequency selective limiter system comprising:
- a first frequency selective limiter (FSL) comprising:
- a first magnetic material having first and second opposing surfaces;
- a first signal conductor disposed on the first surface of the first magnetic material, a width of the first signal conductor decreasing from a first end of the first FSL to a second end of the first FSL along a length of the first FSL;
- and
- two first ground conductors disposed on the second surface of the first magnetic material, a width of a gap between the two first ground conductors decreasing from the first end of the first FSL to the second end of the first FSL along a length of the first FSL;
