The properties of circulators and isolators depend on the choice of the ferrite.

Teledyne Lincoln Microwave’s design knowledge is built on decades of working with ferrite materials and a deep understanding of the interaction between an electromagnetic wave and magnetization within each ferrite type, contributing to optimum system performance.

Waveguide circulators and isolators have by far the best electrical characteristics and can be specified with insertion loss down to less than 0.2 dB in some cases. For microstrip and coaxial circulators and isolators, the insertion loss will typically rise to between 0.5 and 1.0 dB. Note that the wider the bandwidth, the poorer the insertion loss and isolation will be.

In operation, even low loss devices can present a thermal management challenge. Ferrite properties change at elevated
operating temperatures and their performance degrades accordingly. Design for efficient heat dissipation from the ferrite is essential to ensure temperature and performance remain stable. Teledyne Lincoln Microwave achieve excellent thermal stability through design techniques maximizing​ the thermal dissipation from the ferrite material.
