An isolator is a device used for isolating a circuit from a basis of power. An isolator is a motorized swapping device that, in the open site, allows for isolation of the input and output of a device.
RF isolators are 2-port passive devices that help defend radiofrequency mechanisms extreme current or signal reflection. usually used in radar systems wireless communications, distributed antenna systems, test labs, and amplifier systems.
RF isolators cover the frequency range from 8GHz to 76GHz, where the insertion loss from 0.20dB to 1.60dB.Isolation in isolators is from 14dB to 30dB, and VSWR are 1.15:1, 1.25:1, 1.35:1, 1.3:1, 1.4:1, 1.5:1 and 1.6:1.
