Microwave and RF Circulators

RF Circulators from KeyLink Microwave are passive 3-port microwave devices designed to provide isolation between transmit and receive signals for radar, satellite communication, and telecommunication applications. These microwave circulators can control the signal direction and flow inside an RF circuit. KeyLink provides broadband RF circulators spanning the frequency range of 1 GHz to 18 GHz in varying bandwidths, tailored to cover all standard and popular bands commonly used throughout the market place.


KeyLink Microwave specializes in the design, development and manufacturing of a broad range of high quality RF Circulators. These microwave circulators are used to turn a one port diode into a two port device, enabling the negative resistance characteristics of the Gunn diode to be utilized as an amplifier. We proudly offer the markets a broad range of ferrite devices which are unequaled in performance, quality and reliability.
