Alignment method and system for YIG oscillator

摘要

A YIG oscillator is provided having a YIG enclosure with a top housing and a bottom housing, and a YIG sphere magnetically tuned by a permanent magnet. The YIG sphere has a zero temperature compensation (ZTC) axis and is attached to an end portion of a sphere holder. The sphere holder has a mounting surface which is configured to attach the sphere holder directly to the bottom housing of the YIG enclosure. The YIG sphere is aligned with the sphere holder such that the ZTC axis is at a predetermined angle to the mounting surface. A coupling loop is configured to transceive resonance signals to and from the YIG sphere. In one embodiment, the mounting surface is substantially planar and the predetermined angle is zero.
