DEVELOPING OF A HIGH-POWER UNIVERSAL SYSTEM FOR MEASURING ANTENNA TUNERS FOR MATCHING CIRCUITS OF MOBILE CELLULAR COMMUNICATION ANTENNAS
One of the most important problems in modern communication systems is the assessment of higher harmonics in circuit components. Due to the high linearity of the components currently offered, it is necessary to use high power signals for testing. Measurement system has been developed and tested, which allows to measure the higher harmonics and S parameters in amplifiers and antenna tuner switches. The higher harmonics, which are the standard for evaluating the measuring system are presented in LabVIEW software environment, as well as the results of evaluating the harmonics of the device under test. The structural diagram of the developed high power measurement system are shown, as well as the calculation results in the form of graphic images.
