Abstract
Isolators for high frequency signals transmitted between two circuits configured to operate at different voltage domains are provided. The isolators may include resonators capable of operating at high frequencies with high transfer efficiency, high isolation rating, and a small substrate footprint. In some embodiments, the isolators may operate at a frequency not less than 20 GHz, not less than 30 GHz, not less than 65 GHz, or between 20 GHz and 100 GHz, including any value or range of values within such range. The isolators may include inductive loops with slits and capacitors integrally formed at the slits. The sizes and shapes of the inductive loops and capacitors may be configured to control the values of equivalent inductances and capacitances of the isolators. The isolators are compatible to different fabrication processes including, for example, micro-fabrication and PCB manufacture processes.
