ntroduction:
12v Digital LED Radio Station 15W PLL Stereo FM Transmitter 76M-108MHz finished board
Features :
15 w FM stereo PLL FM transmitter kit parts launch module maximum 18 w FM audio frequency control up to 8 km,
This kit includes all the components and circuit boards, but does not include the power supply, antenna, cable, audio cable and coaxial cable.
high-quality FM transmitter
Control panel components: mainly consists of 51 series microcontroller and a dot matrix LCD display screen and a keyboard.
Launch plate parts: digital FM radio chip launch sc3355 + 9018 + 2 + 2 + RD15HV sc2053 level 4 high frequency power amplifier and power regulation components.
Transmitter suite key features:
1, DSP + PLL technology, make the frequency more stable, the frequency does not change with the environment and produce frequency drift.
2, no need any adjustment, bring the fun of DIY to beginners.
3, the frequency can be continuous adjustment within the specified scope.
4, with microphone input interface, and can through digital potentiometer to control the volume of the microphone.
5, audio input by digital potentiometer which can adjust the volume.
6, power can be between 0.1 W and 15 W maximum power continuous adjustment.
7, the power output network for harmonic suppression is very good, make the output spectrum is more clean
8, set the frequency and volume of power lost protection, the next boot does not need to set up again!
Suite main parameters:

About 2, input current 3.0 A
3, the audio signal: the maximum input Vpp is less than 1 v.
4, microphone types: cylinder microphone or microphones!!!!
5, the output power: 0.1 W - 15 W continuous adjustable!
6, the output impedance: 50 Ω
7, working frequency: 76 m - 108 MHZ
Step: 8, frequency of 0.1 MHz
9, the distortion degree: 0.03% ~ 0.1%
A, the board size: fire board: 117 x 70 mm (excluding fin)
Control panel: 58 x 36 mm
B, the launch distance: more than 8 km (premise is open field emission)
C, stereo separation degree: greater than 63 db
