FM Stereo Transmitter using BA1404 IC
The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation (FM) transfers the information by varying the frequency of the carrier wave according to the message signal. Generally, the FM transmitter uses VHF radio frequencies of 87.5 to 108.0 MHz to transmit & receive the FM signal.

A FM transmitter is a device that uses the principles of frequency modulation to broadcast sound supplied at its input. Typical FM transmitter design's usually follow the block diagram below; The signal strength of audio inputs into the transmitter is usually low therefore an amplifier is usually built to bring the signal level up.

To transmit stereo music, FM is enhanced by stereo multiplexing which carries both L and R audio channel content. With the digital age, Radio Data System (RDS) enables FM to carry text information such as traffic, weather, and radio station information which can be displayed on the end-user's device interface.

BH1417 PLL Stereo FM Transmitter simple schematic diagram
Circuit Components: FM Transmitter Circuit Design: Design of Audio Pre-amplifier: Here we are designing a simple single stage common emitter amplifier as the pre-amplifier. a) Selection of Vcc: Here we have selected the NPN Bipolar Junction Transistor, BC109. Since VCEO for this transistor is around 40V, we choose a much lesser Vcc, of about 9V.

The transmitter can then be connected to a source of audio, such as a phone or computer, to broadcast music or other audio content. In this project, I have introduced a compact stereo digital FM transmitter circuit that operates in the frequency range of 87MHz to 108MHz. The frequency can be adjusted using two tactile push-buttons, with a 0.
