频率合成器是射频通信产品的重要组成部分。它们可以在传统的消费产品、个人通信系统和光通信设备中找到。由于频率合成器在许多不同的应用中使用，因此在每种情况下可能需要考虑不同的性能方面。正文描述了分析锁相环频率合成器性能的概念框架，并给出了针对不同性能方面的优化步骤。锁相环特性的分析使用开环带宽和相位裕度的概念来执行，以便能够从设计过程的开始就考虑高阶极点的影响。理论系统分析通过对创新的系统和构建块架构的描述、双极和CMOS技术的电路实现以及测量结果来补充。射频频率合成器的架构包含初学者的基本信息以及有经验的设计师的深入知识。它被广泛地用工业产品中的实际设计实例来说明。作者：电气和电子工程师
Frequency synthesizers are an essential building block of RF communication products. They can be found in traditional consumer products, in personal communication systems, and in optical communication equipment. Since frequency synthesizers are used in many different applications, different performance aspects may need to be considered in each case. The main body of the text describes a conceptual framework for analyzing the performance of PLL frequency synthesizers, and presents optimization procedures for the different performance aspects. The analysis of the PLL properties is performed with the use of the open-loop bandwidth and phase margin concepts, to enable the influence of higher-order poles to be taken into account from the beginning of the design process. The theoretical system analysis is complemented by descriptions of innovative system and building block architectures, by circuit implementations in bipolar and CMOS technologies, and by measurement results. Architectures for RF Frequency Synthesizers contains basic information for the beginner as well as in-depth knowledge for the experienced designer. It is widely illustrated with practical design examples used in industrial products. Written for: Electrical and electronic engineers
