Circulators and Isolators


Capable of significant high power, phase shift circulators provide the heavyweight end of ferrite device operation. Bandwidth limitations are primarily due to the Tee and Coupler, though extended performances can be achieved. Out-of-band requirements should be stated with enquiries.

Coaxial Circulators

An extensive range is available, for frequencies from 400 MHz to 18 GHz.

Resonance Isolators

High power capabilities in the range 1.2 GHz to 6.4 GHz, at up to 5 MW peak power.

Microstrip and Stripline Capabilities

e2v has in-house facilities for circuit preparation using thick and thin film techniques on ferrite and garnet substrates, with a large range of proven devices. e2v can design circuits for your application or print your design on the required substrate materials.


Ferrite junction E&H plane circulators can be configured as isolators (circulators with built-in termination), circulators or as four port device (dual circulators) with optional termination.
