提出了一种适用于多频段、多模式应用的新型可重构功率放大器结构。包括在设计中的是一个可重构的输出匹配网络和可重构的模具。为了验证这一概念的可行性，设计了一个输出功率为33.8dBm/29.4dBm的900 MHz/1.6GHz可重构功率放大器，并将其作为多芯片模块进行了验证。新的拓扑结构使GaAs芯片的尺寸减小了50%，两个或更多服务的模块的尺寸减小了至少20%。该拓扑结构非常灵活，可以轻松扩展以覆盖其他标准。
A novel reconfigurable power amplifier structure for multi-band and multi-mode applications is presented. Included in the design are a reconfigurable output matching network and a reconfigurable die. To demonstrate the feasibility of the concept, a 900MHz/1.6GHz reconfigurable power amplifier with 33.8dBm/29.4dBm output power has been designed as a multi-chip module to validate the multi-band and multi-mode application. The new topology makes possible a 50% size reduction of the GaAs die and at least a 20% size reduction of the modules for two or more services. The topology is flexible and can be easily expanded to cover additional standards.
