Abstract

A band-reconfigurable power amplifier (PA) is presented that comprises band-switchable matching networks with RF microelectromechanical systems switches. The fabricated triple-band PA achieves the output power of 30 dBm and the power added efficiency of 60% in three different frequency bands, 900 MHz, 1500 MHz, and 2000 MHz. Because the proposed band-reconfigurable PA can be extended to a larger number of frequency bands, it will contribute to "band-free" operation for future mobile terminals.

采用MEMS开关的带可重构高效功率放大器

提出了一种由带射频微机电系统开关的带可切换匹配网络组成的带可重构功率放大器。制作的三频段扩音器在900mhz、1500mhz和2000mhz三个不同频段的输出功率达到30dbm，功率增加效率达到60%。由于所提出的频段可重构PA可以扩展到更多的频段，它将有助于未来移动终端的“无带”操作。
