Abstract

An electrically controllable RF-circuit element that includes at least one layer of an electrochromic material sandwiched between two corresponding layers of a solid-electrolyte material and placed adjacent and along a length of RF transmission line. In one example embodiment, the electrically controllable RF-circuit element operates as a tunable band-stop (e.g., notch) filter whose stop band can be spectrally moved by changing one or more dc-bias voltages applied across the corresponding layer stack(s). In another example embodiment, the electrically controllable RF-circuit element operates as a tunable phase shifter whose phase-shifting characteristics can be changed by changing one or more dc-bias voltages applied across the corresponding layer stack(s).
