ITR/SI-Adaptive Integrated Radio Frequency Transceiver Frontends for High Data Rate Wireless Communications

该项目的技术重点是开发一种统一的方法来设计低成本批量制造的自适应射频（RF）收发器前端，目标是实现鲁棒、高速和低功耗的无线通信。这些自适应射频前端适用于高移动性无线电信道或具有可变衰落条件的环境，例如微波和毫米波局域网络，其中人员和物体的运动可能会改变信道的衰减和衰落特性。拟议的研究是材料科学和电气工程的跨学科努力，包括自适应射频前端的开发和表征，包括频率和极化敏捷天线阵列，电子可调谐延迟线，匹配电路和滤波器，所有这些都包含薄膜钛酸钡锶（BST）。BST技术由于其小型化和集成化的特点，提供了许多优于传统设备的优点。本研究调查了用于低成本智能收发器设计的广泛RF器件和组件的开发和特性，包括物理和RF设计，布局，仿真，制造和测试。

The technical focus of this project is to develop a unified approach for the design of low-cost batch fabricated adaptive radio frequency (RF) transceiver frontends with a goal of achieving robust, high speed and low power wireless communications. These adaptive RF frontends are suitable for either high mobility radio channels or environments with variable fading conditions, such as microwave and millimeter-wave local area networks where movements of personnel and objects can vary a channels' attenuation and fading characteristics. The proposed research is an interdisciplinary effort in material science and electrical engineering that encompasses the development and characterization of adaptive RF frontends, consisting of frequency and polarization agile antenna arrays, electronically tunable delay lines, matching circuits and filters all incorporating thin film barium strontium titanate (BST). BST technology provides many advantages over conventional devices because of its miniaturization and integration features. This research investigates the development and characterization of a broad range of RF devices and components for the design of low cost smart transceivers, which entails physical and RF design, layout, simulation, fabrication and testing.
