Fully reconfigurable RF filters for multifunctional and multistandard RF front ends.
Due to the unprecedented growth of wireless communication applications (e.g., 5G), in both military and commercial settings, RF transceivers with multifunctional and multistandard operability are becoming increasingly important. However, the realization of such systems is dependent on hardware that exhibit increased levels of reconfigurability while retaining minimal levels of complexity and size. Among the required components, tunable filters with fully-adaptable transfer functions are needed for proper frequency selection and suppression of undesired noise and RF interference within the receiver chain. The goal of this research project is to design and develop highly-selective single-ended and balanced RF filters that feature multiple levels of increased reconfigurability (e.g., bandwidth and center frequency), are scalable from as low as 500 MHz to as high as 18 GHz, and can be extended to multi-band designs. To maximize the tuning range of the filters, various tuning techniques and schemes will be investigated throughout the project.
