摘要:
Four magnetic layers consisting of upper and lower magnetic layers and intermediate magnetic layers are laminated to form a laminated unit. Two signal lines are disposed side by side between the intermediate magnetic layers, and two ground electrodes sandwich the intermediate magnetic layers therebetween so as to form a transmission line. A dielectric member is disposed between the two signal lines. With this configuration, a common-mode signal is attenuated by utilizing magnetic loss in the magnetic layers. In contrast, by providing the dielectric member, a normal-mode signal is allowed to propagate by reducing the effective relative magnetic permeability while preventing the occurrence of blunt waves.

A non-linear transmission line device includes a magnetic element having at least one end profiled to reduce demagnetisation when the element is biased. The profile may be tapered, stepped, or smoothly curved. Also disclosed is a non-linear transmission device made up of a solid magnetic element, typically of flat rectangular form.

A signal-to-noise enhancer 10 includes a first 90 degree hybrid set 20. A first output end of the first 90 degree hybrid set 20 is connected to an input end of a limiter used a magnetostatic wave element 62a utilized the magnetostatic surface wave mode. Also, a second output end of the first 90 degree hybrid set 20 is connected to an input end of a filter used a magnetostatic wave element 62b similar to the magnetostatic wave element 62a in structure, via a resistor 32 as a first attenuator. Furthermore, an output end of the limiter is connected to a first input end of a second 90 degree hybrid set 40 via a resistor 52 as a second attenuator. Also, an output end of the filter is connected to a second input end of the second 90 degree hybrid set 40.
