YIG Tech Brief

Using small conductive “loops,” a YIG filter is coupled to and from a YIG sphere’s resonant magnetic field. The closer the loop, the wider the bandwidth. Bandwidth can also be expanded by increasing the number of YIG resonators and carefully “tuning” the RF coupling loops. In this brief, RF engineers will learn the three basic methods in which this coupling is applied: signal transfer; signal reflection; and oscillation feedback, and how this differentiates a bandpass from a band-reject filter.
