在这项工作中，我们在以434MHz为中心的ISM频段附近开发了一个射频振荡器，以验证HBAR的温度补偿能力，基于LINBO3和石英单晶板的组合，用于此类目的。 1013和三阶频率 - 温度行为。从载体中测量的1MHz和-165DBC/Hz水平。
In this work, we develop a radio-frequency oscillator operating near the 434MHz-centered ISM band to validate the temperature compensated capability of HBAR based on combining LiNbO3 and Quartz single crystal plates for such purposes. Electrical and thermoelectric characterizations have shown QF product in excess of 1013 and a third order frequency-temperature behavior. A phase noise better than −160dBc/Hz at 100kHz has been measured as well as a −165dBc/Hz level at 1MHz from the carrier. First results showing that the resonator stability is better than 10−9 under room conditions. Further work is expected to lower that level well below 10−10.
