1.5V miniature wireless FM microphone circuit


Posted on Feb 6, 2014

The circuit shown in this paper uses 12 components to form a miniature wireless FM microphone with stable operating frequency, and its transmitting distance is about 30 meters and more than 100 meters at 6V power supply.The circuit is shown as Figure, BG1, C1 and C3 form a high - frequency oscillation circuit. The transmitting distance is related to the curr..
