Field-Shift Isolator
Apr 13, 2018

The field-shift Isolator is based on the different field shifts produced by the ferrite wave patterns transmitted in two directions.

It is added to the side of the ferrite plate attenuation, due to the two-direction transmission of the field caused by different deviations, the electric field that transmits the wave along the forward (Z-direction) is biased toward one side of the attenuation slice, while the electric field along the reverse (+z direction) transmits the wave to the side of the attenuation slice, thus realizing the isolation function of the forward attenuation is very small and the reverse attenuation is very large.

Because of the characteristics of small size, light weight, simple structure and wide working band, the field-shift isolator has been widely used in small power situations.
