Drop-In Circulators

Drop-In Standard Circulators

Drop-In Standard Circulators are essential components in aerospace applications, serving to manage and control the flow of electromagnetic signals within communication and radar systems. These circulators enable efficient one-way signal transmission, reduce signal loss, and protect sensitive equipment from signal reflections, ensuring reliable and interference-free performance in aerospace environments.

Product Specs

Drop-In 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.

Low IMD Designs:  See Note 13
