Gyrator-Function and basics of gyrator

Anisotropic material will have different properties in different directions. The most common materials having anisotropic properties are ferromagnetic compound such as YIG and ferrites. A ferrite is basically a non metallic material.

When a circularly polarized wave is passed through a ferrite rod, under the influence of the axial magnetic field, the axis of polarization will get tilted in the clockwise direction. The amount of tilt depends on strength of the magnetic field as well as dimensions of the ferrite rod. The same principle is being used in the design of gyrator.


The gyrator is one of the ferrite device used in RF and microwave circuit design to obtain phase shift of about 180 degree. It is basically a two port device.

The S matrix of an ideal lossless gyrator and circuit symbol is mentioned in the figure.

The gyrator is basically a phase shifter with 180 degree phase shift.
