Features: This product is basedon the Taylor- Quadrature Product Detector method- to achieve frequency mixing. The clock generator- Si5351 generates two variable frequency orthogonal square wave- signals as excitation, achieving an ultra-low noise ZIF-zero intermediate frequency receiver. The IQ- signal obtained after mixing is output to the CODEC codec and collected- by the MCU, where the DSP algorithm completes signal demodulation and display. DeepSDR 101 is a DSP digital demodulation radio based-on SDR software defined radio architecture. With a 192kHz wide spectrum and waterfall display capability, combined with 16bit sampling, a high dynamic receiver with CW, AM, SSB, and FM demodulation functions is achieved. The entire machine adopts an all aluminum-alloy CNC-shell, paired with a 4.3 inch 800x480 resolution and high brightness IPS- LCD screen. Take it outdoors now and enjoy the natural scenery- and listening-anytime, anywhere!
