Stereo FM Transmitter using BA1404 IC - This is a stereo FM transmitter circuit using an IC from Rohmm semiconductors named BA1404 - which is a monolithic IC and has a built-in stereo modulator, FM modulator, RF amplifier circuitries. This FM modulator can be operated between 76 to 108Mhz. 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. The circuit is powered by a 9V power supply. Transistor Q1 is a high gain audio amplifier that amplifies the sound detected by the electret microphone. The output of Q1 is fed into the frequency modulating circuit created by transistor Q2, inductor L1, and variable capacitor C5. A simple and high quality FM transmitter circuit designed based on the BA1404 IC .This FM transmitter circuit can be operated from a 3 V battery.

FM — frequency modulation. modulator — a circuit designed to add information to a carrier. modulation index pertains to an FM or PM transmitter. The ratio between carrier-frequency deviation (in hertz) and modulating frequency (also in hertz). Stereo FM Transmitter using BA1404 IC - This is a stereo FM transmitter circuit using an IC from Rohmm semiconductors named BA1404 - which is a monolithic IC and has built in stereo modulator, FM modulator, RF amplifier circuitries.This FM modulator can be operated between 76 to 108Mhz. Stereo FM Transmitter using PLL It is a small power fm transmitter that allows data transmission RDS (Radio Data System). Incorporated DSP generates stable stereo signal and attachment RDS data. NS741 applications Wireless microphone Cd and portable mp3 Cell phones NS741 characteristics covered band 76 to 108 MHz stereo modulation RDS transmission Automatic level control The implementation is of this circuit easy. With the BA1404 HI-FI Stereo transmitter, you will be able to transmit MP3 music from your mp3 player, computer, TV / SAT receiver, and many other audio sources. In this ckt mic not use but directly audio input connects with the audio jack. The Ba1404 ic is a good quality digital Fm transmitter.

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. If you need to supply BA1404 FM Transmitter from 12V this simple circuit will do the job. It converts 12V voltage to 3V suitable for BA1404 chip using LM317 voltage regulator. 270 and 390 Ohm resistor determine the output voltage.. BA1404 HI-FI Stereo FM Transmitter broadcasts high quality stereo signal in 88MHz - 108MHz FM band. It can be.
BA1404 is a IC designed for fm mini stereo transmitters. It can be used as a pc fm transmitter, ipod fm transmitter, mp3 transmitter or even car fm transmitter because it has a small pcb dimension ( can fit anyplace ) and maximum 3V power supply. It has a good frequency stability due the high quality 3.5 turns coil and a crystal clear stereo. About The Circuit: These is the exact description of Art Swan, the circuit's Author, "This miniature transmitter is easy to construct and can be picked up on any standard FM receiver. It has a range of up to 1/4 mile or more.
Stereo FM Transmitter with BA1404
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. Working Explanation. Accordingly, the core of the FM stereo transmitter circuit is the BA1404 FM transmitter IC. Generally, the circuit requires just scarcely any expensive parts. However, the information voltage ought to be 1.5V to 3V DC. Moreover, it is recommended to not provide more than 3 volts to the circuit it will harm the IC.
