Toward Fully Electrically Reconfigurable RF and Microwave Technologies with Novel Thin Films and Techniques

The fastest growing wireless communications market has and will continuously see dramatic changes in both the requirements on, and the capabilities of radios to support the wireless connections especially in future 5G technologies.  Tunable technologies are enabling new frontiers for reconfigurable RF and microwave front-ends. Miniaturized multifunctional frequency-agile devices are highly demanded to support multiple communication standards in modern and next generation military and commercial applications.  While the active circuitries are experiencing higher levels of co-integration with the scaling of more advanced semiconductor technology, there are technological barriers of integration to achieve further miniaturized communication systems due to large amount of RF passives on board.

This talk will present the development of frequency agile and fully electrically tunable miniaturized RF and microwave devices with novel thin films and related techniques (i.e., MEMS, on-chip tuning) enabling multifunctional and adaptive radios.  First, the needs and requirements for adaptive and reconfigurable frequency control components in next generation wireless communication systems will be described.  Overview of current tuning techniques (e.g., RF MEMS, ferroelectric and ferromagnetic films) will then be discussed and summarized, followed by the applications of these components in adaptive wireless systems.  Design of transmission line structures with the integration of both nano-patterned ferromagnetic (e.g., permalloy) and ferroelectric (e.g., PZT) thin films will be demonstrated and investigated showing their efficacy as key building elements of fully electrically tunable RF components (e.g., phase shifter, filter, antenna). Finally on-chip tuning techniques and challenges on co-design of active and passive components to enable future 5G communication system will be presented.
