求翻译：对于无源电子标签来说，还涉及到波束供电技术，无源电子标签工作所需能量直接从电磁波束中获取。与有源射频识别系统相比，无缘系统需要较大的发射功率，电磁波在电子标签上经过检波、倍压、存储电路处理，转化为电子标签工作时需的工作电压。是什么意思？

For passive RFID, the technology also involves the beam power, passive RFID tags directly from the energy required to obtain the electromagnetic beam. And active radio frequency identification systems, missed the system needs a larger transmission power, electromagnetic waves in the electronic tag t

There is no source for electronic tags, also involves the beam power supply technology, passive electronic tags work directly from the required energy electromagnetic beam sources. Compared with active RF Identification System, bypassed the transmitter power system needs to be larger in the electrom

Regarding the passive electronic label, but also involves to the wave beam power supply technology, the passive electronic label work needs the energy to gain directly from the electromagnetism wave beam.Compares with the active radio frequency recognition system, does not have the good fortune the

For passive electronic labels, also involve beam power technology, energy required for passive RFID tag directly acquired from electromagnetic beams. Compare with active radio frequency identification system, not systems need a larger transmitting power, the electromagnetic wave on the electronic ta
