Abstract
This paper presents initial results of evaluating
suitability of the conventional two-tone CW passive
intermodulation (PIM) test for characterization of modulated
signal distortion by passive nonlinearities in base station antennas
and RF front-end. A comprehensive analysis of analog and
digitally modulated waveforms in the transmission lines with weak
distributed nonlinearity has been performed using the harmonic
balance analysis and X-parameters in Advanced Design System
(ADS) simulator. The nonlinear distortion metrics used in the
conventional two-tone CW PIM test have been compared with the
respective spectral metrics applied to the modulated waveforms,
such as adjacent channel power ratio (ACPR) and error vector
magnitude (EVM). It is shown that the results of two-tone CW
PIM tests are consistent with the metrics used for assessment of
signal integrity of both analog and digitally modulated waveforms.
