Circulators & Isolators
Ferrite Devices
e2v manufactures Ferrite Devices operating from 350 MHz to 120 GHz, for a wide variety of applications from low cost marine radar to state-of-the-art military devices. Standard units are available in regular waveguide sizes and some special sizes.
e2v offers circulators and isolators as stand-alone units and as part of an integrated microwave package. All come with the assurance that e2v has the facilities to power test units, giving confidence in all devices.
The design and manufacturing facility at Lincoln has an extensive capability and technical knowledge built up for ferrite components. The following is a guide to the range of standard components available.
Waveguide Junction Circulators and Isolators
Covering most standard waveguide sizes and a few specials in H-Plane, E-Plane and Slimline types.
Typical values are shown; actual values will depend on operating conditions. Match and Isolation are given together with achievable bandwidths. For very wideband devices, the losses will increase due to isolation loss. Junction Isolators are circulators with a built-in termination.
Phase Shift Circulators
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.
Table to be inserted
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.
