載波結合技術使用多個較窄頻寬的通道，以達成高速傳輸通訊，面對多載波複雜的可能應用組合，所提出的路由式切換器架構具有足夠靈活度，除此之外，並大幅度減低了電路複雜度，在本次文章中，利用0.18μm之金氧互補半導體製程實現一組路由式收發機，配合載波結合所需要的頻道與頻段，可動態配置射頻路徑，所實現之晶片並經由LTE release 9信號作驗證，以證明所提出架構之可行性。

Carrier aggregation technique combines multiple narrow band channels to achieve a wide bandwidth for high-speed data communication. The proposed router switch architecture reduces the circuit complexity while maintaining the flexibility to meet the requirement of carrier aggregation systems. In this work, two router switch ICs are implemented in 0.18μm CMOS technology to provide dynamic RF paths for carrier aggregation among different channels and bands. The ICs are tested with LTE R9 signals.
