Diseño, simulación y caracterización de un kit decalibración TRL

Abstract

In the development of microwave systems it is important to be able to characterize devices and components in isolation with the least error possible. In this context, TRL (Through-Reflect-Line) calibration techniques are a versatile tool which allows to extract the S parameters of a two-port network minimizing the parasitic effects of measurement circuitry and device mounting. This work presents the design, simulation and measurement of a TRL calibration kit implemented using microstrip lines in a low-cost FR4 substrate. The designed kit is used to extract the S parameters of a capacitor, comparing the simulations with the obtained measurements.
