Ferrite RF isolators and circulators are more than components — they are vital to critical function. Trans-Tech stands as one of the largest manufacturers of microwave ferrite materials worldwide, producing tens of millions of pieces annually for the wireless industry. Our ferrite RF isolators and circulators products range from high-volume garnets for wireless infrastructure to specialized materials catering to radar applications. Our diversity of experience and breadth of materials make our solutions suitable for various applications and requirements.
Applications often require materials that perform optimally in above resonance devices from 100 MHz to around 3 GHz, as well as devices operating below resonance from about 1 GHz to 40 GHz or higher. Our materials cater perfectly to these needs, accommodating a wide range of frequencies and use-cases.
Furthermore, our materials are available for high-power applications and below resonance phase-shifting applications, allowing engineers to choose the most suitable option for your specific project. This flexibility, combined with our long-time expertise and leadership, ensures the delivery of high-quality materials that meet the needs of the ever-evolving wireless industry.

Frequently Asked Questions
A ferrite isolator is a passive RF device that allows signals to pass in one direction while absorbing signals traveling in the opposite direction. It uses a ferrite material to create this non-reciprocal behavior. Ferrite isolators protect sensitive components like amplifiers from reflected power and are essential in wireless base stations, radar transmitters, and test equipment.
An RF circulator routes signals between three or more ports in a specific rotational direction. An isolator is essentially a circulator with one port terminated in a matched load, creating a one-way path. Both use the same ferrite materials and operating principles. Trans-Tech manufactures the ferrite materials and finished devices for both.
Two things: the tightest linewidth specifications in the market, which enables significantly smaller devices, and the consistency that comes from manufacturing tens of millions of pieces annually on purpose-built equipment. We’ve been refining these formulations for decades.
Our portfolio covers above-resonance applications from 100 MHz to approximately 3 GHz, and below-resonance applications from about 1 GHz to 40 GHz and higher. We also supply high-power and temperature-stable materials for specialized radar and military applications.
