摘要：本讲座将讨论相声对无线应用的影响。在概述了设置无线收发器中最具挑战性的相位噪声要求的机制（如本地振荡器的相互混合和调制）后，将通过突出显示相位噪声的最关键来源来分析典型频率合成器的结构。谈话将以阶段锁定循环中涉及相位噪声和耗电量的指标的概述结束。‎

Abstract:
This talk will discuss the impact of phase noise in wireless applications. After an overview of the mechanisms that set the most challenging phase noise requirement in wireless transceivers, such as reciprocal mixing and modulation of the local oscillator, the structure of a typical frequency synthesizer will be analyzed by highlighting the most critical sources of phase noise. The talk will end with an overview of the metrics which relate phase noise and power dissipation in phase locked loop.
