红圈圈的6个元件分别起什么作用，滤波还是阻抗转换，根据什么来调整。
主要是用来滤波的，详细的参数可以参考 CC2530-CC2591EM Reference Design 文件夹下的CC2530_CC2591_EM_Partlist_zip.xls
我在这个论坛里看到如下这段话：
The differential impedance between RF_N and RF_P when CC2591 is terminated as in reference design is approximately (105+J30)Ω at 2440MHz
Optimal CC2530 load impedance for CC2530 is approximately (69+J29)Ω
从这段话看2591和2530的阻抗不匹配，这个滤波器器件参数是怎么考虑的，主要滤除哪个频段的杂波，这几个器件构成滤波器的同时是不是对链路的阻抗也有影响。
您好！你这个文件是哪里看的 叫什么名字 我怎么找不到
