TD-SCDMA: Spectrum Modeling, Experimental Verification of Power Amplifier Nonlinearity

RF Power amplifiers (PA) are critical components in Time division-Synchronous code division multiple access (TD-SCDMA) systems, and PA nonlinearity is one of the main concerns in RF power amplifier designs. This paper presents experimental verification of the spectrum modeling of a RF power amplifier in TD-SCDMA system based on our previous work. The results verify the theoretical spectrum model we derived closely fits the experimental measurements.
