Design of High Frecuency Passive Reconfigurable Circuits


The group has acquired experience and acknowledgement in a new R&D line that is a key point in the development of high frequency communications systems with reconfigurable characteristics (front-ends for RF radio systems defined by software, tunable wireless communications and reconfirgurable satellite payloads). Thus, future passive components (especially filters and multiplexers) with fully reconfigurable electric characteristics (type of response, cnetral frequencies and operational bandwiths), must be developed. In this R&D line, progress is made in the design of circuits in planar and SIW technology (essentially filters) with passaband response of reconfigurable micro-electro-mechanical systems (MEMS) used as switches (discrete tuning elements). The use of new advanced materials (ferroelectrics, quartz crystals and ferrites)with controllable electric and magnetic properties is also investigated. Among the main results of this R&D line, it should be pointed out that a national and internatioal patent has been requested of a "Microwave tunable filter in surface mounted technology based on substrate integrated coaxial resonant cavities", with Ref. PCT/ES2012/070649. The development of this promising R&D line makes use of the group facilities mentioned before, such as full-wave EM simulation laboratory, manufacture and integration of components in planar and hybrid technology, as well as the experimental characterization systems for these high frequency devices.
