Take the receiving process as an example, after the signal enters from the antenna, the process is as follows:
The RF switch determines whether to amplify through a 14dB amplifier
The signal is high pass or low pass filtered by an image suppression filter
Signal processing udrffc5072 chip is mixed to 2.6GHz fixed if
If the range is 2.150ghz-2.750ghz
Signal input MAX2837 chip mixing to baseband, output differential aliqsignal
The MAX2837 chip can limit the signal bandwidth
The max5864 chip digitizes the baseband signal and sends it to cpld and microcontroller for all repair
The LPC4320/4330 processor sends the sampled data to the computer via usb
Put the RFFC5072 and MAX2837 in the shielding cover to protect them from interference from the outside world and other chips on the board, and try to avoid some chips from electrostatic breakdown
