Field programmable microwave circuits have alluded researchers for decades and still remains a highly sought after technology. In the digital domain, Field Programmable Gate Arrays (FPGAs) and other programmable hardware have long been accessible to digital systems designers, with no particular requirements of in-depth knowledge and expertise in the underlining hardware technology. FPGAs for example have enabled high levels of hardware abstraction and helped democratize digital systems design and implementation to a very wide and diverse user community. By contrast microwave circuits/systems are highly static, must often be duplicated or repeated in the same radio to accommodate different frequencies or services and offer little to no hardware re-use and field programmability. Furthermore, their design has remained limited to a relatively small community of experts and is perceived as `Black Magic' by most non specialists. The goal of my proposed research program is to take a holistic approach that can help bring about a paradigm shift in HOW programmable, power efficient microwave circuits can be designed and configured and WHO can do the designing and configuring without requiring in depth expertise nor scaring off new comers to microwave circuit design. This entails the development of new tools and technologies that, together, can bring about such a shift. Specifically, this program will seek to make discoveries along two main thrusts: (i) the tools thrust - through a novel RF/microwave circuit design framework that incorporates hardware abstraction techniques for function based design and hardware synthesis, and (ii) the technologies thrust - through novel devices and fabrication processes to enable design on the fly, programmability and efficient energy use and recycling through thermo-electric generation. On the technology front, the program will be focused on the use of the multilayer Low Temperature Co-fired Ceramics (LTCC) technology coupled with microfabrication (MEMS) techniques and advanced GaN semiconductor devices while on tools front, high-level modern markup languages will be used to capture function-based designs and to implement hardware abstraction strategies. Synthesis techniques that allow mapping of the hardware-abstracted function based designs to the LTCC/MEMS/GaN physical technology platform will also be investigated.
