Abstract :
This paper proposes a wireless sensor network system in a rocket and describes the architecture of sensor tags. The proposed health monitoring system based on the wireless sensor network employs MIMO communication systems, dual-band; 5GHz for downlink and 24GHz for uplink, and dual power sources; vibration and electromagnetic. The paper also demonstrates a GaAs pHEMT 20-30 GHz band low-power consumption amplifier MMIC for the sensor system. At 1V supply voltage, the amplifier achieves a gain of 11.4dB at 24.5GHz. The power consumption and the output 1-dB compression point are 6.16mW and -0.8dBm, respectively. The MMIC achieves the highest performances of reported 24-GHz amplifier ICs.
