2008年11月6日 · mc3361 是FM窄带中放，是对讲机专用IC。 窄带调频，主要是做遥控和语音通信，带宽只有调频广播的1/2左右，所以收听广播时声音干涩。 我使用的是米兹米的FM高频头完成从高频到10.7M的一次变频,滤波后输入到3361与本振10.245M混频,输出的中频455K,经455K滤波器后进行鉴频输出音频,示波器观察中频10.7M和455K的波形都还可以. 问题是:当电台的音频调制信号很小时 (比如主持人暂时没有说话时),455K滤波器输出波形是很漂亮的正弦波, (以下是我的分析) …

2016年2月10日 · The Motorola MC3361 are a series of FM receiver chips. The MC3361 is intended for use in a dual heterodyning receiver, also called "dual conversion". In dual conversion, a first step of electronics lowers the radio frequency (RF) input signal from the antenna to the intermediate frequency (IF).
