A wide spectral range, multi-function adaptive RF front-end for agile spectrum access and RF interference mitigation

RF front-end components based on linear-time-variant modulation of piezoelectric MEMS resonators

“…The lack of adaptive passive front-end filter components based on piezoelectric technologies [94] has shaped the whole mobile radio architecture: accessible to multiple bands are currently relying on solid state switches [111,126], for the most part multiplexing in time the routing of RF signal though the large number of filters, and both time and frequency multiplexing architectures are relying on this analog system, at their back end.…”
