Abstract
A field programmable filter array with high spectral isolation and reconfigurability. A bank of resonators can be programmed at will and on the fly to give any type of filtering response. The order, type and bandwidth of the filter are electronically reconfigured. Each subset of resonators can switch between bandstop and bandpass configurations and form custom filter shapes consisting of combinations of bandstop and bandpass filters. The filter can include a unit cell of a resonator with a series of switches to enable coupling to any of its nearest neighbors. The path in which the flow of energy takes through the array of resonators is dynamic, and the filtering function which is created is dialable on demand.
