LNA, PLL circuit, embedded MCU circuit and UART port.
The RFID Reader Chip is in charge of generating the based Tag
instruction that was modulated into a Transmit Path unit and
demodulate the tag response data from these electronic tags.
MCU unit send a tag operation command to the embedded
MCU of Reader Chip, then the modulation circuit and PLL of
Reader Chip generate the RF Tag instruction for the Transmit Path
unit to send a RF modulate wave to an electronic tag.
Reader Chip unit receive the tag response data from the
electronic tag through the Receive Path. LNA amplifies the tag
signal; the demodulation circuit demodulated the RF tag signal into
a digital signal and decode it into tag data; the embedded MCU
package the tag data, then return it back to the MCU unit for further
process.
 Transmit Path unit
Transmit Path unit is a transmitted channel to amplify and
transmit the RF signal which was modulated by a tag command
from Reader Chip unit, including a power amplifier and a filter
circuit.
