请问50Ω的阻抗匹配是从射频引脚引出后整个电路吗？
您好，
您可以参考帖子：https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/717102/cc1310-rf-trace-impedance-values/2645673?tisearch=e2e-sitesearch&keymatch=50%CE%A9%20cc1310#2645673
The only 50 ohm point in this design is before the pi network for antenna tuning.
此设计中唯一的 50 欧姆点位于用于天线调谐的 pi 网络之前。
如果您有更多PCB硬件设计相关的问题您可以进行硬件审查：https://www.ti.com.cn/tool/cn/SIMPLELINK-SUB1GHZ-DESIGN-REVIEWS?keyMatch=%E7%A1%AC%E4%BB%B6%E5%AE%A1%E6%9F%A5
YES ,请与PCB板材沟通，天线部分与天线厂合作调试。RF才能出较好的效果
