Abstract
To overcome conventional increase of insertion loss and conventional discrepancy of phase characteristic of an S/N enhancer provided for increasing S/N of an electro-magnetic wave to be converted into a magneto-static wave by utilizing saturation of magneto-static wave power propagating through a ferrite thin film, a novel operational principle is used, wherein a large variation of impedance of a strip line, provided for converting electro-magnetic waves into magneto-static waves in the vicinity of saturation of the magneto-static wave. The electro-magnetic wave reflected from the input terminal of the strip line is selectively derived as an output wave through a directional coupling device. As a result, particularly for an electro-magnetic wave applied with wide-band FM modulation, S/N can be remarkably increased without any increase of insertion loss or any influence of phase characteristic discrepancy.
