[Abstract]:The rectifier efficiency of the ultra high frequency label chip rectifier is one of the main factors affecting the communication distance of the label. The common commercial labels are not used for testing ports, and the probe measurement chip circuit method is no longer applicable after encapsulation. Based on the principle of the UHF passive radio frequency identification (UHF-RFID) and the principle of the rectifier's work, the UHF-RFID standard is derived. The relationship between the efficiency of the chip rectifying circuit and the impedance of the chip and the wireless measurement method for the efficiency of the rectifying circuit of the label chip are proposed. The experimental results show that the chip rectifying efficiency is less than 46% when the input power of the chip is within [-18 and -13]d Bm, and the results of the wireless measurement are basically consistent with the probe measurement and simulation results, and the error is less than 4.8% and wireless. The measurement method does not need to destroy the label packaging structure.
