射频收发机（RF Transceiver） 2，既然原来外差的思路是把声音频率的信号，通过混频搬移到高频电磁波频率，那对高频率信号放大的时候，是不是也可以先在比较低的射频频率进行放大，然后再通过频率搬移的方式，将放大后的信号搬移到高频率呢？频率搬移过程中，中间预先设定的固定射频频率被称为“中频”（中间频率，IF，Intermediate Frequency），由于这个频率超出了声音可听的范围，是“超声波”（supersonic），所以被命名为“超外差”（Super-Heterodyne）。混频后的信号在0频率附近，可能会发生DC偏移。阅读详情

没有代码，
全部是用vs2005拉出来的唯一的代码就是一句databind()
