Abstract

The thermal transient effect of a Y-cut langanite (LGN) resonator and a Y-cut langatate (LGT) resonator is measured with various rates of linear temperature-time ramp. The resonators are vacuum-sealed in two-point-mounted or four-point-mounted enclosures. The nominal frequency of the resonators is 10 MHz 5/sup th/ overtone (OT) and the modes from the fundamental to the 7/sup th/ OT are measured. The results show an improvement over AT-cut quartz resonators. The dynamic thermal sensitivity coefficient of the 5/sup th/ OT two-point-mounted LGT resonator is only 15% of that of 5 MHz 5/sup th/ OT AT-cut quartz resonators.
y型朗长石和朗长石的热瞬态效应
在不同的线性温度-时间斜坡速率下,测量了y -切割langanite (LGN)谐振腔和y -切割langanite (LGT)谐振腔的热瞬态效应。谐振器真空密封在两点安装或四点安装的外壳中。谐振器的标称频率为10 MHz 5/sup /泛音(OT),并测量从基波到7/sup / OT的模态。结果表明,与at切割石英谐振器相比,该谐振器有了改进。5/sup / OT两点式LGT谐振器的动态热敏系数仅为5/sup / OT AT-cut石英谐振器的15%。
