Determine whether to amplify via a 14dB amplifier by the RF switch 2. High-pass or low-pass filtering of the signal through the image rejection filter 3. Signal is mixed with RFFC5072 chip to 2.6GHz fixed intermediate frequency 1) The latest firmware supports variable IF options 2) Intermediate frequency range 2.150GHz-2.750GHz 4. The signal is sent to the MAX2837 chip and mixed to the baseband to output the differential IQ signal. 1) The MAX2837 chip can limit the bandwidth of the signal 5. The MAX5864 chip digitizes the baseband signal and sends it to the CPLD and microcontroller. TODO FIXME 6. CPLD 7. The LPC4320/4330 processor sends the sampled data to the computer via USB. 8. Protect the RFFC5072 and MAX2837 in a shield to prevent interference from the outside and other chips on the board, and try to prevent static breakdown.
