我想知道天线匹配是如何工作的。在DA14531数据表中,RF引脚处有一个1.8pF/3.3nH/1.8pF pi网络。这需要引脚到50欧姆吗?
我问的原因是AN-B-027应用笔记也有匹配。是否需要两个匹配网络(数据表中的pi网络加上应用说明中的匹配网络),或者数据表的pi网络是一个占位符,可以被AN-B-027中的匹配所替代?< / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / rf-matching”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >射频匹配< / > < / div > < div class = " field-item古怪”> < a href = " / resource-keywords /数据表”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >数据表< / > < / div > < div class =”field-item甚至“> < a href = " / resource-keywords /应用注释”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >应用程序注意< / > < / div > < / div > < / div > < div class =”字段field-name-field-device field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >设备:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / forum-post-device / da14531”“=“skos:概念”属性=“rdfs: label skos: prefLabel” datatype="">DA14531
