Wideband Characterization of Power Amplifiers Using Undersampling
2009 (English)In: 2009 IEEE MTT-S International Microwave Symposium Digest, 2009, 1365-1368 p.Conference paper (Refereed)
In this paper a radio frequency power amplifier is measured and characterized by the use of undersampling based on the generalized Zhu-Frank sampling theorem. A test system has been designed allowing the bandwidth of the stimuli signal to be 100 MHz in the characterization process. That would not be possible with any vector signal analyzer on the market. One of the more challenging problem within the proposed concept is the model validation process. Here, two different techniques for model validation are proposed, the multitone and the spectrum scan validation methods.
