定义并评估集成混频器本振噪声的劣化能够帮助系统设计人员计算接收机灵敏度的降低蜂窝基站接收机需要在有较高阻塞/干扰信号的情况下接收天线端微弱的有用信号。干扰信号通常会被滤波器滤除,但滤波是在第一级下变频后的中频(IF)阶段进行的。因此,中频滤波器之前的LNA与混频器 Defining and Assessing the Degradation of LO Noise in an Integrated Mixer Helps System Designers Calculate Receiver Sensitivity Decreases Cellular base station receivers need to receive weak, antennae useful signals in the presence of high jammer / jammer signals. The interference signal is usually filtered by the filter, but the filtering is done in the first stage down-converted intermediate frequency (IF) phase. Therefore, the IF filter before the LNA and mixer
