Software Defined Radio SDR Radio Receiver DSP Digital Demodulation CW

Detailed Information About The Product:

Attention: This product is neither an instrument nor a professional radio. Compared with the former two the receiving performance will be slightly inferior. This product realizes frequency mixing based on the Tayloe Quadrature Product Detector method. Clock generator Si5351 generates two quadrature square wave signals with variable frequency as excitation and realizes an ultra-low noise ZIF zero-IF receiver.
The IQ signal obtained after mixing is output to the CODEC codec and collected by the MCU and the DSP algorithm in the MCU completes the demodulation and display of the signal.Tayloe mixer references: Ultra Low Noise High Performance Zero IF Quadrature Product Detector and Preamplifier: http://www.norcalqrp.org/files/Tayloe_mixer_x3a.pdf
