Implementation of TRL (Thru-Reflect-Line) calibration kit for power amplifier measurement

The conventional Short-Open-Load-Thru (SOLT) calibration technique and measurement problem in microwave devices are investigated in this paper. Tremendous development in mobile communication increases the demand for accuracy and performance characterizations of wireless devices over a range of frequencies. Due to this fact, simplified version of calibration technique with better features is developed in order to improve the measurements accuracy. Therefore, the work carried out in this research is to implement a simplified version of Thru-Reflect-Line (TRL) calibration standard kit that matched the requirement of the Power Amplifier(PA). The proposed technique operates in the range of frequency from 2.5Ghz to 2.57GHz in order to improve the gain of the power amplifier in real measurement environment.
