Evaluating nonlinear distortion of single and dual channel excitation of an amplifier at 24 GHz

Experimental characterization of an amplifier's nonlinear properties at 24 GHz is presented in single and dual-band operation using orthogonal frequency-division multiplex signals. A test system for characterizing millimeter-wave frequencies excitation presented. The use standard instrument enables a feasible system. Analytical expressions based on statistical analysis signals hardware impairments were used to analyze the experimental data versus power level found describe well results, including inter- cross-modulation distortion. Parameters are derived that could be studies.
