PCB Wolf-Lite DUC/DDC SDR HF Transceiver All Mode 20W UA3REO TFT 3.5 inch FT8 WiFi

The RF signal is digitized by a high-speed ADC chip and fed to an FPGA processor.
It performs DDC / DUC conversion (digital frequency shift down or up the spectrum) - by analogy with a direct conversion receiver.
The I and Q quadrature signals from the conversions are fed to the STM32 microprocessor.
It filters, (de) modulates and outputs audio to an audio codec / USB. It also handles the entire user interface.
When transmitting, the process occurs in the opposite order, only at the end of the chain there is a DAC, which converts the digital signal back to analog RF.
