Circulators & Isolators

Pioneering protection and reliability

Our low-loss circulators and isolators safely protect microwave generators such as electron vacuum tubes or solid state power amplifiers from reflections that can occur in the microwave applicator. In other words: they isolate the generator. This ensures continuous, stable operation in all types of applicators. Low insertion losses and high insulation make a decisive contribution to improving the service life and energy efficiency of generators and the entire system. This ensures high system availability and reduces operating costs very effectively.

You can find out more about circulators and their areas of application here.

Our products are typically designed to operate safely under worst-case operating conditions such as 100% reflection and all phase conditions. They are almost maintenance-free with a typical service life of well over 10 years.

The performance spectrum of our circulators and isolators is very broadband from 27 MHz to 40 GHz. From the most compact drop-in and SMD components in microstrip line technology to high-performance microwave components in waveguide technology and coaxial line technology.

In addition to standard circulators and isolators for S-band and X-band LINAC applications as well as for industrial microwave applications, radar systems and satellite communications, we develop customized products according to all your requirements and needs. From components to assemblies to subsystems. All key components from a single source.
