Ferromagnetic tuning ring for YIG oscillators |
摘要 |
A YIG oscillator is provided having a YIG sphere magnetically coupled to a permanent magnet, a field straightener, and a ferromagnetic ring. The field straightener is attached to the permanent magnet and has a predetermined circumference. The ferromagnetic ring is configured to fit around the predetermined circumference of the field straightener. The ferromagnetic ring fine-tunes the magnetic field combination of the permanent magnetic and the field straightener. A coupling loop is configured to transceive resonance signals to and from the YIG sphere.
