چکیده
Radio Frequency (RF) power amplifiers (PAs) have large memory effects and high nonlinearity.It is very important to analyze the system level performance of PAsaccurately using a simple behavioral or mathematical model.This paper proposes a system-level behavioral model for RF PA that exhibit memory effects.This model gives quite accurate results in predicting the behavior of PAs with memory effects.The proposed model is implemented in Agilent software. Description of memory effects and an accurate presentation of highly nonlinear characteristics based on the single-tone transfer characteristics for PA are presented. Gain for circuit level model and behavioral model is calculated.

FPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects
Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...
