摘要：
Aiming at the expansive application of RFID technology, design considerations are expatiated to a highly-integrated, multimode, power-controllable transmitter in mobile UHF RFID reader with CMOS process. The transmitter consists of digital section, a baseband circuit, an up-conversion mixer and a gain-variable power amplifier. Multiple data modes can be generated. The direct-conversion RF section is proposed to minimize the off-chip components and provide a low-cost, highly efficient solution. The RF power amplifier can achieve a maximum output power of 26dBm and maintain a power-added efficiency (PAE) higher than 40% over the 18dBm-26dBm output power range. Feasibility of the transmitter is validated by ADS simulator.
