Abstract
A reliable DPI measurement is proposed to investigate the IC immunity above 1GHz. The direct RF power injection (DPI) method is reviewed, and the concern for extending frequency range is discussed. Details of the measurement setup are reported in this work. The critical part, on-board injection network, in the power injection path is realized with a 3dB bandwidth of 14.5GHz. A low dropout regulator is used to demonstrate the test and setup. The proposed DPI measurement above 1GHz is validated by the experimental results.
