Abstract:
We comprehensively present the application considerations of thermocouple-based microwave power sensor, including the influences of illumination, working time, working circle, and different fabrication process batches on the output performance, for evaluating the reliability and feasibility of the power sensor in practical applications. The thermocouple-based microwave power sensor is fully compatible with the GaAs monolithic microwave integrated circuit (MMIC) technology. The measured results show that the illumination increases the sensitivity of the power sensor and the output performance does not deteriorate with the working time and working circle. There exists some small differences between the different batches of power sensors but do not influence its usage. Therefore, we can make a conclusion that the power sensor can be applied to measure microwave power in practical applications and a proper package is recommended to avoid illumination. Furthermore, high reliability membrane-based thermopile can be used to recovery the waste heat of RF devices like power amplifier.
