A YIG oscillator (240) is provided having a YIG enclosure (42,46) and a YIG sphere (12) magnetically tuned by a permanent magnet (46). The YIG sphere (1 2) is attached to an end portion of a sphere holder (202). The sphere holder (202) has a mounting surface (208) which is configured to attach the sphere holder (202) directly to the bottom housing (44) of a YIG enclosure (42,46). The YIG sphere (12) is aligned with the sphere holder (202) such that a zero temperature compensation (ZTC) axis (122) is at a predetermined angle to the mounting surface (208). A coupling loop (16) is configured to transceive resonance signals to and from the YIG sphere (12).
