With the rapid development of RF devices, the requirements for their testing techniques are becoming stricter and stricter. Due to the large errors introduced by the test fixtures during the testing process, it is necessary for a suitable calibration algorithm to eliminate them. For eliminating errors, in this paper, the SOLT calibration algorithm and the TRL calibration algorithm are selected for mathematical derivation, and establish a mathematical model. According to the mathematical derivation of the calibration algorithm and the simulation using Matlab, consequently, the correctness of the SOLT calibration algorithm and the TRL calibration algorithm is verified. It is concluded that the SOLT calibration algorithm is more suitable for the low frequency bands test of the non-coaxial RF device test fixture, while the TRL calibration algorithm is more suitable for high frequency bands test of non-coaxial RF device test fixture.
