Yklhsocneg SDR Radio Receiver DSP Digital Demodulation CW/AM/SSB/FM/WFM

The whole machine adopts all-aluminum alloy CNC shell, with a 4.3-inch 800x480 resolution high-brightness IPS LCD display. It also maintains a compact and compact body. Immediately take it to the outdoors, enjoy the natural scenery and the of the radio anytime, anywhere!Base Parameters: Display technology: 4.3 inch IPS 800x 480; DC dimming bright LCD Description: -01 is a 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. Attention: This product is neither an instrument nor a professional radio. Compared with the former two, the receiving performance be slightly inferior. This product realizes frequency mixing based on the Tayloe Quadrature Product Detector . 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 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://.norcalqrp./files/Tayloe_mixer_x3a.pdf Control : resistive touch screen + encoder, Frequency range: 100k~149MHz
