HEX3653 76MHz-108MHz Stereo FM Radio Receiver Module

HEX3653 76MHz-108MHz Stereo FM Radio Receiver Module

HEX3653 76MHz-108MHz Stereo FM Radio Receiver Module, FM radio program is rich, good sound quality. FM scanning radio pocket computers kit using 1.8-3.6V working voltage, the circuit includes an FM radio receiver from the antenna to the frequency divider output audio signals, also has a search tuning circuit, signal detection circuit, mute circuit and frequency locked loop FLL circuit compression frequency offset. If the frequency of the circuit is designed as 70KHZ, peripheral circuits without intermediate frequency transformer, here the frequency is selected by a built-in RC circuit IF filter to complete. After the circuit is powered on, press the power button, the circuit starts to work, press the SEEK + button for high-frequency or low-end radio frequency search, automatic search for radio signals, tuning will automatically stop, then click the Search button if the circuit continues to search for radio stations. Frequency range is 76-108MHZ.

PCB Size: 5.5x3.7cm

Works with 2xAA 1.5V batteries (not included).
