Kit is not include antenna. Item description: This circuit is the core of BH1417F phase-locked loop FM stereo application-specific integrated circuit.The integrated circuit is made up of improve the signal-to-noise ratio (S\/N) pre-emphasis circuit, prevent over modulation limiter circuit, control signal input signal frequency of the low-pass filter circuit (LPF), produce the stereo composite signal, FM stereo modulation circuit launch phase lock loop (PLL) circuit, etc.BH1417F frequency characteristic is excellent, it can reach 40 db separating degree, transmission quality can be comparable to the local FM radio.Part due to the high frequency oscillation frequency synthesis circuit is adopted, so the oscillation frequency is very stable, and can easily change the transmission frequency.And it sets up the pre-emphasis circuit, limiting circuit and low-pass filter can significantly improve the sound quality, its total harmonic distortion is 0.3%, the RF output level is 100 db. Chip: BH1417F Frequency: Low-end (87.7MHz\/87.9MHz\/88.1MHz\/88.3MHz\/88.5MHz\/88.7MHz\/88.9MHz) High-end (106.7MHZ\/106.9MHZ\/107.1MHZ\/107.3MHZ\/107.5MHZ\/107.7MHZ\/107.9MHZ) Input power: 12V 200mA Transmit power：5V 100M Stereo Separation: 40dB Total Harmonic Distortion:0.3％ RF level:100dB Applications: forward wireless music players, TV audio. 14 operation Frequencys can select by DIP switch. 1  L L L L 87.7MHZ 2  H L L L 87.9 MHZ 3  L H L L 88.1 MHZ 4  H H L L 88.3 MHZ 5  L L H L 88.5 MHZ 6  H L H L 88.7 MHZ 7  L H H L 88.9 MHZ 8  L L L H 106.7 MHZ 9  H L L H 106.9 MHZ 10 L H L H 107.1 MHZ 11 H H L H 107.3 MHZ 12 L L H H 107.5 MHZ 13 H L H H 107.7 MHZ 14 L H H H 107.9 MHZ Debugging, the qua.Find many great new \u0026amp; used options and get the best deals for Digital Radio Station PLL Stereo BH1417F FM Radio Transmitter DIY Kit at the best online prices at Order2india Shopping!
