DeepSDR 101 Software Defined Radio Receiver
Product description
DeepSDR 101 is a DSP digital demodulation radio based on SDR software-defined radio
architecture. It has a 192kHz width spectrogram and waterfall display capabilities, and
cooperates with 16bit sampling to realize 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 display, while maintaining a
compact and compact body.
Immediately take it to the outdoors, enjoy the natural scenery and the fun of listening
anytime, anywhere!

Receiver Block Diagram
This product realizes frequency mixing based on the Tayloe Quadrature Product Detector
method. 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 and collected by the MCU, and
the DSP algorithm in the MCU completes the demodulation and display of the signal.

Attention points
1. The machine adopts SDR architecture. If there is a strong broadcasting station near
you, the phenomenon of mirror radio may appear.
2. The input impedance of the antenna interface is 50Ω. For the medium wave radio, it
is recommended to connect a dedicated medium wave loop antenna for better listening
effect.
3. Please pay attention to the volume setting of the earphone (EAR) before using the
earphone to listen to avoid discomfort caused by excessive volume.
