FM 15W Stereo PLL FM Transmitter Kit Frequency Adjustable Volume DIY

FM 15W Stereo PLL FM Transmitter Kit Frequency Adjustable Volume DIY

Description:
- control panel components: 51 computers and dot-matrix LCD display and keyboard.
- transmitter board components: digital FM transmitter chip +9018 +2 SC3355 +2 OF SHANXI + RD15HV four high-frequency power amplification and power conditioning components.
- transmitter kit main characteristics:
- DSP + PLL technology to make more stable frequency, the frequency does not change with the environment and produce frequency shift.
- without any adjustment to bring the fun of DIY beginners.
- the frequency can be adjusted continuously within a predetermined range.
- with a microphone input interface, and can control the volume of the microphone through digital potentiometer.
- Audio input through the digital potentiometer to adjust the volume.
-  power can be adjusted continuously between 0.1W to a maximum power of 15W.
-  the power output of the network harmonic suppression is very good, so that the output spectrum cleaner
- set the frequency and volume has a power-down protection, the next boot do not need to re-set!

 
The kit main parameters:
- input voltage: DC 12V
- Input Current: 3.0A
- the audio signal: maximum input Vpp is less than the 1V.
- microphone type: cylinder microphone or a microphone!
-  the output power: 0.1W-15W continuously adjustable!
- the output impedance: 50Ω
-  the operating frequency: 76M-108MHz
- Frequency Step: 0.1MHz
-  the distortion degree: 0.03% to 0.1%
- Board size: emission plate: 117 x 70mm (without heat sink)
                                Control panel: 58 × 36mm
- Launch distance: more than 8KM (if open field emission)
