Do you want to DIY make a 5w fm transmitter yourself ?
Come with me, get our 5w fm transmitter PCB kit suite
The spare parts kit is set, buyers need to self-welding (some difficult welding chip, we have already welding, they buyer do not need to worry about it), After welding, you can use it without any debugging.
Kit Description:
FM transmitter DIYER should request a special design of the shop without any debugging of 7W FM transmitter. Requires that you are a novice or a veteran, as long as you weld, you can DIY a 100% success of high-quality FM transmitter.
Now on the transmitter to make a brief introduction:
◆ panel components: mainly by the 51 computers and dot matrix LCD display and keypad.
◆ transmitter board components: digital FM transmitter chip +9018 +2 SC3355 +2 SC2053 +2 SC1971 four high-frequency power amplification and power conditioning components.
◆ Transmitter Kit Features:
1, DSP + phase-locked loop technology, the more stable frequency, the frequency will not change with the environment arising from the frequency drift.
2, without any adjustment to bring the fun of DIY beginners.
3, the frequency can be adjusted continuously within a specified range.
4, with a microphone input interface, and can be controlled via digital potentiometer microphone volume.
5, the audio input through the digital potentiometer can adjust the volume.
6, the power to 0.5W maximum power can be adjusted continuously between 7W.
7, the power output is very good harmonic suppression network, the output spectrum cleaner, under the reference picture.
8, the transmitter digital switch, you can always control the transmitter to work and stop working.
9, set the frequency and volume with a power-down protection, no need to set the next boot!
Suite main parameters:
1, input voltage: DC 12V
2, the input current: 1.0A or so
3, the audio signal: input Vpp less than 1V.
4, microphone type: cylinder microphone or microphone!
5, the output power: 0.5W-7W adjustable!
6, output impedance: 50Ω
7, the operating frequency: 76M-108MHz
8, the frequency step: 0.1MHz
9, Distortion: 0.03% to 0.1%
a, board size: transmitting plate: 100 × 60mm
Panel: 60 × 36mm
b, emission distance: more than 5KM (provided that the open area firing)
c, Stereo separation: greater than 63db
