With BA1404 HI FI Stereo transmitter you will be able to transmit MP3 music from your iPod, computer, discman, walkman, TV SAT receiver, and many other audio sources. The above FM transmitter design is a result of many hours of testing and tweaking.
The circuit is based on the IC BA1404 from ROHM Semiconductors. BA1404 is a monolithic FM stereo modulator that has built in stereo modulator, FM modulator, RF amplifier circuitry. BA1404 FM transmitter can be operated from 76 to 108MHz and power supply for the circuit can be anything between 1.25 to 3 volts.
The above FM transmitter design is a result of many hours of testing and tweaking. The goal was simple; to test many existing BA1404 transmitter designs, compare their performance, identify weaknesses and come up with a new BA1404 transmitter design that improves sound quality, has very good frequency stability, maximizes transmitter’s range, and is fairly simple for everyone to build.
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.
Circuit of stereo FM transmitter of of high quality using integrated circuit ba1404 for mp3, mp4, ipod, computer, radio of the car. Transmit of your equipment of portable audio for the radio of your car, transmitters of fm of low potency are the ideal for transmission wireless of audio sign for fm receivers.
