RF/Microwave Circulator & Isolator Series

Home > Circulators & Isolators

An RF isolator is a two-port passive device made of magnets and ferrite material which is used to protect other RF components from excessive signal reflection, while an RF circulator is a three-port passive device used to control the direction of signal flow in a circuit. MECA offers thirty models of isolators and circulators in both N & SMA-Female connectors with average power ratings from 2 - 250 watts. The most “popular” frequency bands between 0.8 - 18.0 GHz are readily available and can ship from STOCK to 4 weeks after receipt of your order. IP 67 compliant isolators available.

Notes:
1. Isolators are designed with an internal 2W load capability and 50 W for our High Power IP 67 series.
    Consult factory for application information.
2. Higher Isolator power levels can be achieved utilizing our circulators with an external load. MECA carries an
    extensive selection of high power loads. Please consult with a MECA applications engineer to discuss
    your requirement.
3. Isolation performance contingent on a VSWR of 1.05:1 Max. on terminated ports.
4. Circulator power rated into a load mismatch of 1.05:1 all phase angles.
5. Additional frequency ranges available, please consult with factory for specific ranges.
6. Heat sink temperature must not exceed the maximum operating temperature specified.

Application Note
Isolator/Circulator basic theory and definitions, common applications, power ratings, special handling and storage considerations.
