REV 2.2 Page 1 of 3 Copyright © 2020 The SFI0418 is a single junction isolator offering a forward and reverse power rating of 10 Watts CW over an operational frequency band of 4 to 18 GHz. This coaxial isolator uses SMA female connectors on all ports and has a minimum of 15 dB isolation. Fairview Microwave offers a wide variety of isolators to fit your needs. These are two-port devices that transmit microwave or radio frequency power in one direction only and block the signal in the opposite direction. They can be thought of as a diode for RF energy. Isolators are used to isolate equipment from the effects of conditions outside of the equipment. For instance they are used to prevent a microwave source being detuned by a mismatched load. Fairview Microwave’s isolators feature excellent insertion loss, high isolation and reliability.
