What is YIG Oscillator?
A YIG Oscillator consists of a sphere made from a single crystal of synthetic yttrium iron garnet mounted on a rod that is positioned inside of a magnetic field and acts as the resonator. The magnetic field is generated by either a permanent or electromagnet. The intensity of this field determines the frequency that the YIG sphere resonates.
The advantage of YIG oscillators is that they can be tuned over a very wide frequency range and provide the lowest phase noise for broadband microwave applications.
Important parameters when looking for a YIG Oscillator:
- Operating Frequency: It is the range of frequencies at which a YIG oscillator can oscillate. They can operate in the range from 3 to 50 GHz.
- Magnet Type: YIG oscillators can have different kinds of magnets generating the magnetic field for the YIG sphere. Oscillators with an electromagnet can be tuned over a range of frequencies by adjusting the magnetic field. Oscillators with a permanent magnet can be tuned and oscillate over a single frequency.
- Phase Noise: It is the noise arising from the rapid, short-term, random phase fluctuations that occur in a signal and may cause variations in the frequency at which a YIG sphere oscillates.
