摘要
介绍频率综合器指标要求,在比较频率合成常用方法的基础上描述一种具有三通道输出的小步进超宽带频率综合器实现构架,推导和分析关键设计参数表达式,计算理论性能指标,给出各个通道的详细实现方案。基于国产器件完成样机设计和测试。测试结果表明该频率综合器具有超宽带频率输出、低相位噪声、低杂散、低谐波、细步进输出等特点,满足指标要求。
The indicator requirements of the frequency synthesizer are introduced. On the basis of the common methods of frequency synthesis,the framework of a small stepping UWB frequency synthesizer with three output channels is described. The expressions of the key design parameters are deduced and analyzed,and theoretical performance index is calculated. The detail implementation scheme of each channel is given. The prototype design and test were completed,which relyed on the domestic devices. The test results show that the frequency synthesizer has UWB frequency output,low phase noise,low stray,low harmonic,small stepping output,etc,which meet the indicator requirement.
