A Novel Black Box Based Behavioral Model of Power Amplifier for WCDMA Applications
In this paper, Black Box approach is presented for behavioral modeling of a non linear power amplifier with memory effects. Large signal parameters of a Motorola LDMOS power amplifier driven by a WCDMA signal were extracted while taking into considerations the power amplifier's bandwidth. The proposed model was validated based on the simulated data. Some validation results are presented both in the time and frequency domains, using WCDMA signal. The introduction of the third generation UMTS, based on WCDMA technology, is a further step towards satisfying the ever increasing demand for data/internet services. 3G is quickly moving on to 3.5G, 3.9G, and 4G and is changing the way the world communicates.
