摘要
设计了一个工作频段902~928MHz、输出功率19dBm、功率增益高达27dB应用于射频识别(RFID)系统的驱动级功率放大器。运用了仿真优化和实际测试相结合的方法快速、成功地设计了该放大器。对完成匹配后的功率放大器进行仿真优化,得到了满足设计指标要求的匹配参数,再根据这些匹配参数构建实际的功率放大器,并对放大器进行实际测试,测试结果与仿真结果高度一致。实际测试结果表明,运用这种方法设计的功率放大器完全满足设计要求,可以很好地应用在RFID系统中,从而改善系统的性能。
A drive stage amplifier for RFID system was designed with a rapid and successful approach combing simulation optimization with practical test. The PA works at 902 - 928 MHz, output power is 19 dBm, power gain is up to 27 dB. The amplifier was simulated and optimized to get matching parameters which fulfill the design goal. Then the obtained matching parameters were used to build up the practical amplifier, and the amplifier was tested at practical condition, the test and simulation results were well fit. It reveals that this PA fully proves the design goal and it can be used in RFID system to improve the performance of the system.
