An Improved Design of Feed-forward Power Amplifier
Amplifiers nonlinear phenomenon is the significant factor that affects the performance of radio & microwave communication system. In this paper, the principle of feed-forward technology and various improved solutions are introduced. Meanwhile, aiming at their shortages of classic feed-forward and OCFF topology, a new high linearization solution is proposed for the large power output, which reduces difficulty of the error amplifier design and input power. The results show it can improve the power efficiency remarkably without adding the complexity of the system, which is of practical value for improving the communication quality.
