YIG Technology

How yttrium iron garnet resonators, tuning coils and drivers work, and how YIG oscillators and filters compare with VCO, DRO and cavity alternatives.

The physics and practical behaviour of YIG-based devices, from resonator and tuning-coil fundamentals to phase noise and test methods.

Read what YIG is first if the material is new, then how YIG oscillators work for the two-coil loop. The two comparison pages state a conclusion rather than a hedge: YIG oscillator vs VCO vs DRO and YIG filter vs cavity filter.

Device-level specification — the numbers you put on a drawing — stays in the component guides.

How YIG Oscillators Work

A YIG-tuned oscillator is a negative-resistance active device locked to a magnetically tuned resonator, with a coil driver doing most of the work you actually specify.

YIG Filter vs Cavity Filter

Use a YIG-tuned filter when the passband must move and stay a roughly constant absolute width. Use a cavity when the band is fixed and insertion loss or power handling binds.

YIG Oscillator vs VCO vs DRO

When a YIG-tuned oscillator, a varactor VCO or a DRO is the right microwave source — decided by tuning range, hop speed and close-in phase noise, not by a headline dBc/Hz figure.
