Ultrahigh frequency miniature RFID reader/writer module

The invention discloses a super-frequency mini RFID read-write module, comprising a DSP, a PLL frequency synthesizer, a storing chip, a communication port, an antenna port and a circulator. The module also comprises a RF sending channel formed by a DAC, a modulator and a power amplifying unit which are sequentially connected in series and a RF receiving channel formed by an LNA, a RF VGA, a demodulator, an IF VGA and an ADC which are sequentially connected in series. The PLL frequency synthesizer is respectively connected with the modulator and the demodulator. The DSP is connected with the PLL frequency synthesizer, the storing chip, the communication port, the ADC and the DAC. A DSP system-software is pre-set in the DSP to realize the functions of the read-write module. The module reduces the volume of the read-write module and reinforces the function of the read-write module.
