| Abstract: | Reader module of radio frequency smart card is the kernel of RF smart card reader. A complete design and adjustment method of it, including its encode ,decode, modulation ,demodulation, power amplifier of output RF signal, voltage amplifier of input RF signal, comparator etc. is presented. Several issues about electro-magnetic compatibility are also discussed. The effective operation distance to a single RF card can reach 10cm. |
