| 摘 要： | 为得到低相噪的X波段微波信号,运用微波倍频技术的原理设计了一种频率源。分别针对双极晶体管和场效应管倍频电路进行了具体分析和工程调试。最终完成的频率源实现了低相噪性能,相噪指标为-87 dBc@100 Hz,-102 dBc@1 kHz,-110 dBc@10 kHz。测试结果表明倍频电路除损失理论上的相位噪声外,基本不附加噪声。

| Abstract: | A design of frequency source is given using the working principle of microwave frequency multiplier in order to obtain a low phase noise X band microwave signal.The circuits of frequency multiplier using BJT and FET are analyzed concretely and debugged respectively.The frequency source achieves a low phase noise with measurement results of -87 dBc@100 Hz,-102 dBc@1 kHz and -110 dBc@10 kHz,showing that the frequency multiplier can hardly add noise other than the theoretic phase noise loss. |
