Microwave hexaferrites
Hexaferrites occupy a special place among the microwave magnetic materials. They
feature high magnetic anisotropy (17 kOe) and are recommended for the use in millimeter
wave isolators and circulators workable at frequencies 10 GHz through 100GHz. Hexaferrites
permit to create miniaturized yet discrete microwave devices that do not require a
permanent biasing magnets in the component package.
High density hexaferrites are ideal for MIC application and microstrip mm-wave devices.

Microwave ceramics
The series of MT (Mg, Ti) and MTS (Mg, Ti, Si) ceramic dielectrics were developed for
use as matching medias in microwave application. Materials with any dielectric
permeability values other than listed below are available on request within stated e’ ranges.
BT (Ba, Ti) and ZST (Zr, Sn, Ti) series feature high dielectric constant, high density,
and low loss values. They are well suited for high Q dielectric resonators.
The fine surface finished parts of these materials are available and recommended as
substrates for microwave integrated circuits (MIC) application.
