The board is an excellent performance of the PLL FM stereo transmitter board, it can modulated and transmit the stereo signal of computer sound card, video game, CD, DVD and MP3, such as a stereo audio signal transmission modulation transmitter, the board also contains two microphone amplifier circuit, work with ordinary FM stereo radio receiver and can achieve high fidelity FM stereo transmission. Suitable for the production of wireless stereo speakers, wireless microphones , wireless headphones , CD, MP3, DVD, PAD, notebook computers and other wireless audio adapter.

The core of the circuit is BH1417F PLL FM stereo transmitter ASIC. The integrated circuit components are circuit to improve the signal to noise ratio (S / N) of the pre-emphasis circuit for preventing signal overshoot of the limiter circuit , the control input signal frequency low-pass filter circuit (LPF), a stereo composite signal to generate a stereo modulation circuit PLL FM transmitter circuit (PLL) and so on. BH1417F frequency characteristics is excellent , it can achieve separation of 40dB , the sound quality is able to compare with the local transmission of FM radio . Since the high-frequency oscillating part is a frequency synthesizer circuit, the oscillation frequency is very stable and can easily change the transmission frequency . And it sets the pre-emphasis circuit , limiter circuit and a low -pass filter can significantly improve the sound quality , the total harmonic distortion reached 0.3%, RF output level is 100dB.

BH1417F is suitable for mainland China 87 ~ 108MHz FM broadcast band , can adjust the frequency by the parallel data set, frequency section is divided into low and high two parts , and high segments, each part can be set seven frequency points , a total of 14 frequency points . Frequency set points can be referenced under the showing.
