Máy khuyếch đại công suất 1W RF cho FM iPOD
Mạch này các pác có thể tham khảo bằng tiếng anh:
The transmitting signal can the be picked up by any FM radio receiver. Most often used in cars. [separator]The problem with most FM transmitter is that they have very weak signal and short transmitting range. Some units are so bad that even when they are placed really close to the receiver, you barely receive the signal. This photo show the Stereo FM transmitter. Wire to left is for audio input and wire to right is the modified RF output signal. The transmitting signal is just a few micro watt and that is no good, right :-) This project will change that dramatically
