The objective of this program is to increase use of low cost CMOS technologies in super-GHz frequency applications to make benefits of communication techniques available to a larger cross section of the population. Successful implementation of RF switches along with progress made by others could make a fully CMOS-based single chip radio a reality, which could significantly lower costs of wireless telephones, local area networks, global positioning systems and others. This program should also provide insights to ease the transition of mainstream digital integrated circuit technologies to the super-GHz frequency range. The research program will implement RF switches, a key RF building block of radios, using low cost bulk CMOS technologies. More specifically, this program will, (1) characterize bulk CMOS processes and develop models for required components, (2) evaluate and understand model parameters which limit performance, (3) identify physical causes for the limitations, and (4) discover approaches to overcome these limitations to implement high and moderate-power RF switches operating at 900 MHz and possible at 2.4 GHz with performance acceptable for typical ISM band applications.

该计划的目标是增加超GHz频率应用中低成本CMOS技术的使用，使通信技术的好处可用于更大的人口截面。 射频开关的成功实现沿着其他方面的进展，可以使完全基于CMOS的单芯片无线电成为现实，这可以显著降低无线电话、局域网、全球定位系统和其他系统的成本。 该计划还应提供见解，以缓解主流数字集成电路技术向超GHz频率范围的过渡。 该研究计划将使用低成本的大规模CMOS技术实现射频开关，这是无线电的关键射频构建模块。 更具体地说，该计划将，（1）表征体CMOS工艺和开发所需组件的模型，（2）评估和理解限制性能的模型参数，（3）识别限制的物理原因，和（4）发现克服这些限制的方法，以实施高和中等-功率RF开关工作频率为900 MHz，可能工作频率为2.4 GHz，性能可接受，适用于典型的ISM频段应用。
