【摘要】 阶跃管倍频器是铷原子钟温度敏感性的重要因素,通过试验测定和研究了铷原子钟阶跃倍频器温度敏感性的规律,研究了阶跃倍频器温度敏感性对铷原子钟频率稳定度的影响。测试结果表明,随着阶跃倍频器温度的升高,阶跃倍频器的输出功率逐渐减小,在温度较高的条件下微波功率输出变化越大;温度敏感性对铷原子钟稳定度的影响主要是由于温度变化引起了阶跃倍频器输出微波功率发生变化,产生了微波功率频移。更多还原

【Abstract】 The high order microwave frequency multiplier is the important factor for the temperature sensitivity of rubidium atomic clocks.Experimentation is carried out to study the temperature sensitivity of the high order microwave frequency multiplier,and the temperature sensitivity of the high order microwave frequency multiplier influence to the rubidium atomic clocks was also studied.The test results indicate that the power of high order microwave frequency multiplier decreased gradually as the temperature was enhanced,and the higher of the temperature for the microwave frequency multiplier,the more transformation of the output power of the microwave frequency multiplier.The microwave frequency multiplier temperature sensitivity influence to the rubidium atomic clocks was due to microwave-power frequency shift from microwave frequency multiplier caused by temperature.更多还原
