The BH1415F is a FM stereo transmitter IC that transmits simple configuration. The IC consists of a stereo modulator for 

generating stereo composite signals and a FM transmitter for broadcasting a FM signal on the air. The stereo modulator 

generates a composite signal which consists of the MAIN, SUB, and pilot signal from a 38kHz oscillator. 

The FM transmitter radiates FM wave on the air by modulating the carrier signal with a composite signal. 

Applications
