Simple long-distance wireless FM microphone circuit


Posted on Feb 6, 2014

The the loop antenna L1 for emission also serves as the oscillation coil, the high-frequency current flowing in antenna is synchronized resonance with the oscillation frequency, so it is always in the best emission state. Accoring to practice, launching distance is about 100 ~ 150m in empty mine. In contrast, in the case of equal working voltage, current and..
