چکیده
Abstrac t An interlaboratory comparison of microwave power measurement (project UME-EM-10-02) was carried out among eight (8) laboratories in Turkey. In this comparison, it was requested to make microwave power measurements at +10 dBm, 0 dBm and -15 dBm power levels with 0.03 GHz, 1 GHz, 7 GHz, 12 GHz and 18 GHz frequencies with their own measurement systems and methods. The measurement results and the expanded uncertainties were presented by the participant laboratories. Also, the normalized score (En) of each participant laboratory were calculated and presented to evaluate the performance of the laboratories. Most of the results in measuring power on a type N coaxial line show good agreement. According to the calculated En values, corrective actions were proposed to some of the participant laboratories.

Applications of Artificial Neural Networks to RF and Microwave Measurements
This article describes how artificial neural networks (ANNs) can be used to benefit a number of RF and microwave measurement areas including vector network analysis (VNA). We apply ANNs to model a variety of on-wafer and coaxial VNA calibrations, including open-short-load-thru (OSLT) and line-reflect-match (LRM), and assess the accuracy of the calibrations using these ANN-modeled standards. We ...
