Biplanar tapered line frequency selective limiter

A method for forming a frequency selective limiter, the method comprising:

• providing a magnetic material having first and second opposing surfaces;
• disposing a first conductor on the first surface of the 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
• disposing two second conductors on the second surface of the 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;
• a second frequency selective limiter (FSL) comprising:
• a second magnetic material having first and second opposing surfaces;
• a second signal conductor disposed on the first surface of the second magnetic material, a width of the second signal conductor decreasing from a first end of the second FSL to a second end of the second FSL along a length of the second FSL;
• and
• two second ground conductors disposed on the second surface of the second magnetic material, a width of a gap between the two second ground conductors decreasing from the first end of the second FSL to the second end of the second FSL along a length of the second FSL,
• wherein an output of the first FSL is coupled to an input of the second FSL.
