LTE(长期演进技术)和LTE-Advanced(长期演进技术升级版)已被世界上大部分移动运营商选为它们下一步蜂窝网络演进的方向。ITU-R(国际电信联盟无线通信委员会)制定了一套移动通信4G技术规範，即IMT-Advanced(高级国际移动通信)技术规範。LTE-Advanced正式满足了IMT-Advanced技术要求并且向後兼容LTE。而LTE-Advanced 3GPP Release 11的标準版本V11.8.0也在2014年3月发布。在这个项目中，我们会开发一个LTE-Advanced射频收发器芯片来满足LTE-Advanced 3GPP Release 10 和11的标準要求，支持数据速率高达300/100 Mbps (下行/上行)。该收发器芯片支持从450 MHz到3.8 GHz的广阔频段，因而覆盖了世界上主要国家和地区，比如中国、香港，美国，欧洲，日本，澳洲及英国。我们会开发实现LTE-Advanced射频收发器的关键技术，比如，载波聚合，高阶多输入多输出，包络跟踪，和宽带可重构射频前端等等。我们计划了两次流片来开发矽验證的IPs。作为这个项目的成果，我们会交付LTE-Advanced射频收发器的芯片，参考设计，专利及IPs。这个项目将非常有助於香港在区域内建立并发挥技术领先的作用，帮助本地的IC设计公司，无线宽带方案公司，OEM和ODM的製造商创造竞争优势。
