HamGeek DSP-01 4.3" SDR Radio Receiver DSP Digital Demodulation CW/AM/SSB/FM/WFM

Description: Description HamGeek DSP-01 SDR Radio Receiver DSP Digital Demodulation CW/AM/SSB/FM/WFM with 4.3" IPS LCDAttention:This product is neither an instrument nor a professional radio. Compared with the former two, the receiving performance will be slightly inferior. Your order represents that you have a certain understanding of the technical implementation and functional limitations of this product, and may need to take certain risks. For example, returns and exchanges caused by products that cannot meet your psychological expectations.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 Preamplifierhttp://www.norcalqrp.org/files/Tayloe_mixer_x3a.pdfDescription:HamGeek DSP-01 is a DSP digital demodulation radio based on SDR architecture. It features a 192kHz wide spectrogram and waterfall display. With 16bit sampling, it is a high dynamic receiver with CW, AM, SSB and FM demodulation functions.
