The broader impact/commercialization potential of this project include tunable blocks that would allow a range of spectrally- and spatially-agile devices. These may include high-gain directional antennas that can improve performance while reducing power consumption. The fundamental MEMS varactor technology also offers solutions for critical efficiency and linearity problems as wireless devices employ more complex waveforms. Furthermore, the fundamental switching element in the varactor addresses a significant market need in the $200+ million automated test equipment (ATE) market.This Small Business Technology Transfer Research (STTR) Phase 2 project will develop tunable power amplifiers for handset applications based on an enabling microelectromechanical systems (MEMS) varactor technology. The successful completion of the proposed effort will allow the team to address significant market needs for reducing the cost and part count of smart phones and wireless devices, and high bandwidth testing needed for automated test equipment (ATE). The methods to be employed include optimizing the MEMS varactor and integrating the varactor into a tunable power amplifier. The proposed tunable approach addresses the high degree of redundancy in wireless designs today. In many cases, a complete front end and antenna, hardwired for a specific frequency, must be replicated for each band. The proposed approach enables tuning a single channel to cover the spectrum, drastically reducing the bill of material and footprints.

该项目更广泛的影响/商业化潜力包括可调模块，这将允许一系列光谱和空间灵活的设备。这些可能包括高增益定向天线，可以提高性能，同时降低功耗。 基本的MEMS变容二极管技术还为无线设备采用更复杂的波形时的关键效率和线性问题提供了解决方案。此外，变容二极管中的基本开关元件满足了2亿美元以上自动测试设备（ATE）市场的巨大需求。该小型企业技术转移研究（STTR）第2阶段项目将开发基于微机电系统（MEMS）变容二极管技术的手机应用可调谐功率放大器。成功完成拟议的工作将使该团队能够满足减少智能手机和无线设备成本和部件数量的重大市场需求，以及自动测试设备（ATE）所需的高带宽测试。所采用的方法包括优化MEMS变容二极管和将变容二极管集成到可调谐功率放大器中。 所提出的可调方法解决了当今无线设计中的高度冗余问题。在许多情况下，必须为每个频段复制针对特定频率硬连线的完整前端和天线。所提出的方法能够调谐单个通道以覆盖频谱，从而大幅减少材料和占地面积。
