Description
2FSK Audio Signal Input 60MHz-150MHz Adjustable Car FM Modulator Amplifier Board FM Broadcast Transmitter Module
Product Description
KW_FM-2FSK modulation module is a modulation transmitter module with integrated VCO, the center frequency range is 50M to 160M, it can do FM and 2FSK modulation, and the carrier frequency is 50MHz-160MHz. The FM input uses the rf port as the audio or modulation signal input, and the FM center frequency can be adjusted with a potentiometer. The module supports 2FSK signal modulation. This module is easy to use, input FM or 2FSK signal through signal, set center frequency or FSK frequency modulation frequency by adjusting potentiometer, that is, the input signal will be modulated and output. This module has high cost performance and is very suitable for various manufacturers, companies,
universities, and scientific research institutions.

Operation instructions

FM modulation: Test the center frequency of the output signal before inputting the FM modulation signal, and the potentiometer can be adjusted to modify the center frequency, increase the frequency clockwise, decrease the frequency counterclockwise, and the amplitude of the input signal determines the maximum frequency deviation. 2FSK modulation: The module defaults to output 2FSK-L signal, and the FSK-L potentiometer can be adjusted to modify the frequency, increasing the frequency clockwise and decreasing the frequency counterclockwise. When a high level is input, the module outputs a 2FSK-H signal, and the FSK-H potentiometer can be adjusted to modify the frequency, increasing the frequency clockwise and decreasing the frequency counterclockwise.
Remarks: The output of the module is not a standard sine wave. The FM and FSK modulation and demodulation signals mainly require frequency signals, and there is no requirement for waveforms.
