摘要

大多数微波功率标准采用量热法技术来校准热敏电阻安装的有效效率作为传输标准。量热计的校正系数是关键系数。为了纠正传输线功率损耗对量热计热电堆的影响,通常会在安装座的输入端口前放置薄铜平箔以终止信号,从而将传输线(包括热隔离部分和接口法兰)分开,并将被测件中的射频功率消耗掉。平板箔短片的反射系数测量是热量计总测量不确定度的主要不确定因素。本文介绍了一种新的评估技术,可以合理地降低校正因子的不确定性。该技术基于电磁场理论计算短路的射频耗散功率。对其原理和结果进行了详细的分析。

Correction factor evaluation technique for a rectangular waveguide microcalorimeter
Most microwave power standards adopt calorimetry techniques to calibrate the effective efficiency of a thermistor mount as transfer standard. Correction factor of the calorimeter is the key coefficent. To correct the influence of the power loss of the transmission line to the thermopile in the calorimeter, a thin copper flat foil will usually be put before the mount's input port to terminate the signal, as so to separate the transmission line (including the thermal isolation section and the interface flange) and foil dissipate RF power from the DUT. The flat foil short's reflection coefficient measurement is the main uncertainty contributer of the total calorimter measurement uncertainty. In this paper, we introduce a new evaluation technique which will reasonably reduce the correction factor uncertainty. The technique is based on electromagnetic field theory to get the short's RF dissipation power. The detailed analysis of its princple and results are provided.
