 既然您已理解了这个概念，那么让我们假设这样的情景：您马上抓起一个PA前往离您最近的实验室，为获得一个规定的I DSQ 电流值而对栅极进行偏置。经过一些负载线分析后，您选择了一个q点，并用该信息来对该PA的栅极进行偏置。成功了</description><dc:language>zh-CN</dc:language><generator>Telligent Community 13</generator><item><title>回复:射频（RF）基站的幕后故事（第2部分）</title><link>https://e2echina.ti.com/blogs_/archives/b/precisionhub/posts/rf-2</link><pubDate>Wed, 30 Sep 2015 06:33:28 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:5f21abfd-c2f3-495d-9c86-4a435c0762a2</guid><dc:creator>user1830873</dc:creator><slash:comments>0</slash:comments><description>&lt;p&gt;功耗和信号增益找到很好的平衡点，论述的有理有据，让人敬佩&lt;/p&gt;
