TUNER CHARACTERIZATION METHODS AND APPARATUS

摘要

Embodiments include methods and apparatus for characterizing a tuner. For a given tuner, a processing system is adapted to measure scattering parameters for a plurality of characterization points that are non-uniformly distributed across a Smith chart, and to store the scattering parameters in a tuner characterization file. Interpolation and extrapolation processes are performed to determine additional scattering parameters for a plurality of additional characterization points, which are also stored in the tuner characterization file.
