摘要/Abstract：
Aiming at the specified protocol of EPC global Class-1 Generation-2, design considerations are expatiated to a novel structure of transmitter front-end for mobile RFID reader with 0.18um CMOS process. The transmitter front-end consists mainly of an up-conversion mixer, a linear power amplifier (PA) and a non-linear PA. Controlled by the reader’s working status, the implemented scheme can transmit high efficient carrier or linear ASK modulation data at separate periods. The linear PA can provide a power gain of 16.3dB and a 1dB output power of19dBm. The non-linear PA can achieve 1dB output power of20.6dBm and a maximum power-added efficiency (PAE) of44%. The output waveform and spectrum are tested to verify the feasibility of the designed transmitter.
