2017年8月3日 · Here is a very easy DIY FM receiver circuit diagram. It is easy to build FM receiver circuit as the TA2003 IC used here, comes in easy DIP package. It’s both Am and FM receiver IC, we’ll use FM, so FM circuit is only given.

2007年1月13日 · 问下楼上各位大侠,我看ta2003电路较简单,有点象ta8164,问下能用它来做简易fm接收机.对讲机的接收电路?

2020年5月29日 · For good selectivity you need proper RF design, with decent high-level double-balanced mixer and a quality LO with low phase-noise - single chip solutions will never perform very well by comparison. However you may be able to enhance the performance with a good tracking pre-selector.

2011年5月9日 · ta2003的fm部分已有一个本振和乘法混频器，还差一个振荡器，看内部图其fm高放部分是一只三极管，刚好可以用来制作振荡器。 于是就制作了这个扫频信号发生器，分三段：0-50Mhz、80-120Mhz、120-180Mhz，经测试可输出100毫伏的信号，需要再加一级隔离放大，以输 …

2017年8月3日 · The TA2003P is a highly integrated AM/FM radio receiver IC, very close to CD2003GP. You can find TA2003P datasheet, pinout and other details here. Uses fewer …

2023年9月9日 · Here is a simple FM Radio Receiver Using single chip TA 2003. This IC have inbuilt RF Amplifier, local oscillator, a mixer, FM detector and AF preamplifier.

2013年5月10日 · I assembled a cheap Chinese AM/FM radio kit 208HAF based on the CD2003 chip, a TA2003 clone. All works as might be expected for the low price but on AM the sound is a bit course, like all is overmodulated. Is there an easy way to fix this? I would settle for less volume as it is loud enough.

2017年5月15日 · 主要是不知道ta2003内部本振极和混频极的连接关系，我还是将12脚接上正极或悬空两种方案都试试再说。 如果再加一极本振，改为二次变频那是更好，可我怕控制不好高频自激，造成制作失败。
