Abstract
An impedance matching device that is particularly suited for high speed, high power applications is disclosed. The impedance matching devices employ magnetic coupling allowing their usage in a "frequency-agile" environments such as communication as well as communication jamming and deception techniques without creating high current, high voltage and thermal conditions that might otherwise damage the related switching devices. The impedance matching device provides a predetermined impedance to transform a load impedance Z.sub.L into a desired characteristic impedance Z.sub.0 over a frequency range having a lower and an upper band. The device comprises one or more first and second inductive components. Each of the first inductive components has an impedance characteristic associated with said lower band, whereas each of the second inductive component has an impedance characteristic associated with the upper band. The device further comprises switch means having an active and an inactive state and being of a predetermined number at least equal to the predetermined number of second components. Each of the switch means in its active state bypassing its corresponding second component and…
