摘要

先進長程演進計畫（Long term evolution advanced, LTE-A）利用載波聚合（Carrier aggregation, CA）技術，將多個子載波（Component carriers, CCs）結合，以達成高速傳輸通訊，為實現此種技術，在本文章中以0.18 μm金氧半互補式半導體製程（CMOS process）實現一載波聚合調變器，並以兩組頻寬為10 MHz的LTE-A訊號來測試此晶片之同頻帶（Intra-band）與跨頻帶（Inter-band）之載波聚合，其量測的輸出頻譜以及錯誤向量振幅（Error vector magnitude, EVM）符合LTE-A之需求。

LTE-Advanced uses carrier aggregation (CA) of multiple component carriers (CCs) to achieve high-bandwidth transmission. To fulfill such technology, the novel carrier -aggregated modulator structure is proposed. In this work, the carrier-aggregated modulator is implemented in 0.18 μm CMOS technology and tested with two 10 MHz LTE-Advanced Release 10 signals to demonstrate the feasibility of the proposed architecture in both the intra-band and inter-band CA. The measured output spectrum and EVM meet the LTE-Advanced requirements.
