Sample sircuit FM Transmitter

This Simple Portable FM transmitter includes a limiter, a microphone amplifier and a PLL digital tuning. All the components are placed on one circuit board. The RF power is switchable between 1 W (HI) and 0,2 W (LO).

Radio Transmitter

Fm radio transmitter circuit above is one of the radio transmitter circuit is quite simple andeasy to make. Transmission distance can reach is about 2km. The circuit above uses a transistor and none use the IC so cheap enough to be a trial. Power supply requiredbetween 9 volts to 24 volts, the transmitter circuit 24 volt supply reaches the maximumtransmit power.
