Product Overview:
The DeepSDR 101 is a high-performance DSP digital demodulation radio based on an advanced SDR (Software-Defined Radio) architecture, featuring real-time spectrum and waterfall plot display capabilities at 192kHz. It employs Taylo quadrature mixer technology and a zero-IF (ZIF) receiver design, combined with 16-bit high-precision ADC sampling, to achieve ultra-low noise and high dynamic range signal reception. It supports multiple demodulation modes including CW, AM, SSB (LSB/USB), WFM, and stereo FM, making it suitable for amateur radio (HAM), shortwave listening, and FM broadcasting. The entire unit features an all-aluminum alloy CNC-machined casing, a 4.3-inch high-brightness IPS touchscreen, and a multi-functional encoder, making it highly portable and suitable for outdoor use.

Application Scenarios:
Amateur Radio (HAM) CommunicationShortwave Broadcast Reception, FM Stereo ReceptionField Exploration, Outdoor Travel ListeningRadio Teaching and Experiments

Technical Support:
Based on the Taylo Quadrature Product Detector method, mixing is implemented using a Si5351 clock generator to produce two variable-frequency orthogonal square wav signals as excitation, achieving an ultra-low noise ZIF zero-IF receiver. The resulting IQ signal after mixing is output to the CODEC codec and acquired by the MCU. Demodulation and display of the signal are then performed using a DSP algorithm within the MCU.
