The invention discloses a
gallium-
arsenide-based thermoelectric-photoelectric micro sensor in a self-powered
radio frequency transceiver module. The
gallium-
arsenide-based thermoelectric-photoelectric micro sensor is of an array structure composed of a plurality of identical sensor modules. Each sensor module is provided with a plurality of sets of thermoelectric couplers connected in series. The hot end of the sensor is placed on a heat concentrated portion (radiating plate) of a power
amplifier, and the cold end of the sensor is far away from the heat concentrated portion and is close to an outer
metal shell (
heat sink plate), so that the larger
temperature difference is formed between the hot end and the cold end. Direct-
current voltage output is generated on the
sensor array on the basis of the Seebeck effect, and the direct-
current voltage conducts battery charging and
energy storage on a battery to be charged. A PN junction is manufactured on the top of a
semiconductor thermocouple arm of the sensor, a current path forward direction ordered arrangement is formed, the
heat sink plate above the PN junction is provided with holes so as to increase the illumination area, and the photoelectric micro sensor capable of collecting
light energy is formed. Compared with a traditional self-powered sensor collecting single energy, the
gallium-
arsenide-based thermoelectric-photoelectric micro sensor in the self-powered
radio frequency transceiver module can collect
light energy and
heat energy at the same time to achieve the self-powered function, is smaller in size, and greatly improves power supply capability. In addition, the heat radiated when the
radio frequency transceiver module works is effectively absorbed, and the radiating performance of the radio frequency transceiver module is improved.
