BH1417  DIY Kit
Feature:        
 
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.
 
Parameter:
 
Chip: BH1417F
Frequency:
Low-end (87.7MHz/87.9MHz/88.1MHz/88.3MHz/88.5MHz/88.7MHz/88.9MHz)

BH1417F 5V 12V
Feature:
 
Size: 80x45mm
Working voltage: 5 12V
Antenna length: 1m
Transmission distance: 50-100 meters (open space)
The transmitter board adopts exquisite double-panel, high quality, high-quality high-frequency dedicated electronic components, and the PCB pads are tinned to ensure the quality of welding. The assembled products can be directly put on the market. The quality of non-general student training kits is comparable.
Features: Convert stereo audio signal input into FM radio transmission FM radio transmission, realize the function of wireless transmission of stereo audio signal, pilot system FM stereo transmitter.
 
The high frequency circuit adopts PLL FM stereo transmitter integrated circuit chip BH1417F (or replaces BH1416F by itself), the working frequency is quite stable, because the fuselage does not produce induced frequency drift, the working frequency is set by DIP switch control. If BH1416F, the transmitting frequency can be debugged. The lower end of the seven frequencies 76.8, 77.0, 77.2, 77.4, 77.6, 77.8, 78.0 are optional or optional high 88.0, 88.2, 88.4, 88.6, 88.8, 89.0, 89.2 seven frequencies, using a one-meter antenna to transmit distance to open areas About 100 meters; if BH1417F, the transmission frequency can be debugged at the low end or high frequency 87.7, 87.9, 88.1, 88.3, ​​88.5, 88.7, 88.9 7 106.7, 106.9, 107.1, 107.3, 107.5, 107.7, 107.9. Just change the code to replace the DIP switch code. Suitable for teaching or school counseling students radio broadcasters to assemble, install and debug complete specifications (including schematics, assembly drawings), without audio transmission lines.
