| 摘 要： | 设计了一种采用阶跃恢复二极管来实现的、用于被动型铷原子频标的微波高次倍频器。调试结果表明:该倍频器的输入信号频率为90MHz;倍频次数为76;输出信号频率为6 840MHz;输出功率为-18.2dBm;对邻近谐波抑制度为28.75dB。该倍频器接入铷原子频标后,能实现闭环锁定,符合小型化铷原子频标的要求。

| Abstract: | A high-order microwave frequency multiplier is designed by adopting the step recovery diode for a passive rubidium atomic frequency standard.The debugging result shows that the input signal frequency is 90MHz;the order of multiplication is 76;the output signal freguency is 6 840MHz;the output power is-18.2dBm;the rejection ratio to the adjacent harmonics is 28.75dB.When this multiplier is linked with the rubidium atomic frequency standard,the close-loop locking can be realized.Thus this multiplier satisfies the needs of miniature passive rubidium atomic frequency standard. |
