Notes:
a. Pulse test; pulse width
≤
300 µs, duty cycle
≤
2 %.
b. Guaranteed by design, not subject to production testing.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

射频识别(Radio Frequency Identification，RFID)技术是一种利用无线射频通信实现的非接触式自动识别技术，与目前广泛采用的条形码技术相比，RFID具有容量大、识别距离远、穿透能力强、抗污性强等特点。RFID技术已经发展得比较成熟并获得了大规模商用，但超高频RFID技术相对滞后。本文分析了射频芯片nRF9E5的功能特性，并将其用于RFID系统中，设计了一套有源超高频(...[详细]
