通过对国内外13.56MHz频段RFID读写设备频率和发射功率限值的简单介绍人手,以案例及实验为主分析了符合相关法规、RFID标准要求的设备,无论是否通过直连电网电源、均可能导致附近电源线中传导骚扰超过GB9254标准限值的情况,从而得出产品适用GB9254标准时,如带RFID模块,须将有意发射及其谐波去掉后进行符合性判定。
通過對國內外13.56MHz頻段RFID讀寫設備頻率和髮射功率限值的簡單介紹人手,以案例及實驗為主分析瞭符閤相關法規、RFID標準要求的設備,無論是否通過直連電網電源、均可能導緻附近電源線中傳導騷擾超過GB9254標準限值的情況,從而得齣產品適用GB9254標準時,如帶RFID模塊,鬚將有意髮射及其諧波去掉後進行符閤性判定。

The limit of radiated power level for RFID in 13.56 MHz frequency band was discussed first.By case and testing mainly,the results showed the conducted emission of ITE with RFID module at AC main terminal may exceed the limit specified in GB9254 whether the EUT was powered by AC source directly or not,even if EUT conformed with relevant regulations and standards for RFID devices,the active emis sion frequency and its harmonious frequencies should be neglected when ITE with RFID module was tested according to GB9254.
