Ultra Broadband 10-W CW Integrated Limiter

A method for limiting the power of an input signal having an input impedance, comprising the steps of:

• (a) transforming the input signal from the input impedance to an intermediate impedance;
• (b) shunting a portion of the input signal to ground;
• and
• (c) transforming a remaining portion of the input signal from the intermediate impedance to an output impedance.

An impedance transformer, comprising:

• (a) a first node;
• (b) a second node;
• (c) a ground node;
• and
• (d) a rectangular array of at least four conductors connected between the first node, the second node, and the ground node, wherein each conductor in the array is electromagnetically coupled to each other conductor in the array by at least one of side-coupling and broadside coupling.
