摘要：
A novel wireless sensor network system with compatibility of microwave power transmission (MPT) using a Gallium Nitride (GaN) power amplifier has been fabricated and tested. The sensor node operates using electrical power supplied by the MPT system. Time-and frequency-division operations are proposed for the compatibility. Under the frequency-division operation, receiving signal strength indicator of 285 dBm and packet error rate of,1% were measured when the available DC power of a rectifier with 160 mW output power. Under 120-min measurement, sustainable power balance between radio-frequencyDC conversion and power consumption in stable operation of the sensor node was achieved.
