RF Front-End of Digital Communication System (Software-Defined Radio)

The RF Front-End is a bridge between an analog RF signal and a FPGA for any wireless communication devices and measurement tools. The module performs analog signal processing in both RX/TX directions. The receiver has a one channel and the transmitter can generate I/Q channels.

The RX channel performs hardware signal processing: the analog signal is filtered, amplified, being sampled and processed by an analog-to-digital converter(ADC). The prepared digital signals forwarded to the FPGA for digital signal processing (DSP). In the TX channels: the digital signals from the FPGA are converted to analog signal by digital-to-analog converter(DAC), filtered and amplified. The clocking signal is genarated by a low-jitter oscillator and synchronized with the FPGA clock.

The module designed to work with DE1-SoC Board (SoC FPGA+ARM Altera Cyclon V), but it can be connected to any board with FPGA throw general connectors.
