内容：就个人而言，我是不折不扣的资深菜鸟——两重含义，一个是喜欢射频很多年（从童年开始），依然不甚懂，另一个是虽然不甚懂、但初衷未改，依然喜欢、痴迷。,其实这就是我们这个版块的目的：做明白人，或者，做一个“比以前更明白的人” 我们可能会相对比较集中探讨的是射频中的矢量测量、天馈（包括balun——平衡器），将来不排除还会涉及到频谱分析、自动电桥、,射频阻抗分析仪等。,哪怕学电子专业，射频也是比较抽象、深奥、难懂的，感谢胡树豪老先生、《ARRL天线手册》、上海李璐（bg4GZU,制作了一批n2pk给大家解馋，注：n2pk硬件是开源的）、ceeliu（大红点驻波表作者）,4ilp戏言：“主要是拿来装b，没个VNA，你都不好意思跟人说是射频爱好者”，其实他说的没错！

内容：ADC的SNR相同，则4片ADC取平均可将系统SNR提高6dB8片取平均可将系统SNR提高约9dB而联发科的WiFi无线路由器芯片在WiFi5的时代，却和高通一样恶心ADC是独立在收发芯片里的(集成了射频前端,直到，如今160MHz带宽的WiFi 6E的到来看了一眼，联发科Filogic 830(MT7986A)居然破天荒的采用“通过IQ通道连接射频前端”的方案ADC全部可以为我们所用。

内容：yuhang 发表于 2014-8-1 10:10 射频最烧钱的是仪器，手头20G的设备好久没用了，一直用单位的俺们业余玩玩的，就不晒仪器了。。。
