Standard Circulators

All catalog part numbers are for devices with clockwise rotation, however, counter-clockwise rotation is available by request. Consult the factory for special performance and unique mechanical configurations. We have many other designs no listed in the catalog, and develop new designs on a frequent basis.

Encapsulation is available on some designs for high peak power & high altitude capability.
