Evaluation and validation of a national WR-15 (50 to 75 GHz) power measurement system

In this paper, we present some preliminary results from evaluation and validation of a national WR-15 (50 to 75 GHz) power measurement system, which has been upgraded for thermistor sensor (thermistor mount) measurements recently. The system is a physical realization of direct comparison transfer technique for microwave power sensor calibration. It has been evaluated and validated referring to a WR-15 microcalorimeter measurement system. Good performance has been observed preliminary, and some necessary improvement works have been planned in near future.
