This product is based on the Tayloe Quadrature Product Detector method to achieve frequency mixing. The 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.

Product Description:
DeepSDR 101 is a DSP digital demodulation radio based on SDR software defined radio architecture. With 192kHz wide spectrogram and waterfall display capabilities, combined with 16bit sampling, it realizes a high dynamic receiver with CW, AM, SSB, FM demodulation functions. The whole machine adopts an all-aluminum alloy CNC shell, with a 4.3-inch 800x480 resolution high-brightness IPS LCD screen, while maintaining a small and compact body.
