FM Transmitter Module Board 2FSK Audio Signal Modulation Signal Input 50M-160M Adjustable
Description:
KW_FM-2FSK modulation module is a FM transmitter module with integrated VCO, the center frequency is 50M to 160M. It can be used for FM and 2FSK modulation, and carrier frequency is 50MHz-160MHz.
FM input adopts SMA port as audio or modulation signal input, and FM center frequency can be adjusted by potentiometer. The module supports 2FSK signal modulation. It is easy to use the module. By inputting the FM or 2FSK signal through the signal port, and adjusting the potentiometer to set the center frequency or FSK frequency, the input signal can be modulated and output.
This module is cost-effective and is very suitable for various manufacturers, companies, universities, and scientific research institutions.
Parameters:
- Module Power Supply: 15VDC
- Output Impedance: 50Ω
- Output Power: 3-10dBm
- Input FM Signal Amplitude: 0.5-12Vpp
- FM Center Frequency Range: 60MHz-150MHz

- 2FSK Input Maximum Frequency Hopping: 150MHz
- 2FSK Input Minimum Frequency Hopping: 60MHz
- 2FSK Maximum Carrier Rate: 300KHz
- 2FSK High Level: 1-12V
- 2FSK Low Level: 0-0.2V
- Size: 64mm * 44mm
- Location Hole: M3
- Hole Center Edge Distance: 4mm
Operation Instructions:
- FM Modulation: Test the center frequency of output signal before inputting the FM modulation signal. Adjustable potentiometer to modify the center frequency. Turn clockwise to increase the frequency, and turn counterclockwise to decrease the frequency. The amplitude of the input signal determines the maximum frequency offset.
- 2FSK Modulation: The module outputs 2FSK-L signals by default. Adjustable 2FSK-L potentiometer to modify the frequency. Turn clockwise to increase the frequency, and turn counterclockwise to decrease the frequency. When high level is input, the module outputs 2FSK-H signal. Adjustable 2FSK-H potentiometer to modify the frequency. Turn clockwise to increase the frequency, and turn counterclockwise to decrease the frequency.
Note: The output of the module is not a standard sine wave. FM and FSK modulation and demodulation signals mainly require frequency signals and have no requirements on waveforms.
Package Included:
- 1 x FM Transmitter Module
