针对TD-SCDMA系统的要求，成功设计了TD-SCDMA 10W功率放大器。设计过程中比较了S参数优化设计和大信号LOAD-PULL设计的仿真结果，指出了对于功率放大器，应该按照大信号设计方法进行。最后，依据仿真结果，制作了放大器并进行了测试。

A high linear 10W power amplifier is designed to reach the specification of TD-SCDMA system. In the paper, two design methods, S parameter optimization and LOAD-PULL method are compared. The results show that LOAD-PULL method is more accurate for design high power amplifier. The amplifier is fabricated and measured, the ACPR is better than -40dBc, PAE >10% when output power is 10W.
