| Feedforward Linearization of a Power Amplifier for Wireless Communication Systems | ||
| Abstract | ||
| in this paper detailed simulations based on Applied Wave Research (AWR) will be introduced. This work will demonstrate the applicability of the feedforward technique to linearize the behavior of a power amplifier used in wireless communication systems. The linearized amplifier is a parametric model for AWR that takes into account actual operating characteristics of a commercial unit used for multicarrier transmission. In this paper the linearity of power amplifier will be improved, the third-order intermodulation products (IMD3) will be less than (-42dBc) and the intermodulation distortion cancellation reaches 24dB. The operation bandwidth is more than 125MHz, the carrier frequency 5.8 GHz and maximum output power is great than 30dBm. | ||
