摘要
A coupling structure for a ferrite-based resonator comprises a short, stiff mounting rod and ferrite sphere are mechanically coupled to a substrate that provides support for a stiff coupling loop. The structure reduces differential movement between the sphere and the coupling loop, thereby reducing vibration-induced degradation of resonator performance. This resonator structure may be used in tunable, wideband oscillator, filter, or amplifier circuits, for example. In one embodiment, the mounting rod is a poor thermal conductor, thereby thermally isolating the sphere, which becomes nearly isothermal.
