Abstract
Embodiments of a single-chip ScAIN tunable filter bank include a plurality of switching elements, and a plurality of channel filters integrated on a monolithic platform. The monolithic platform may comprise a single crystal base and each of the switching elements may comprise at least one of a scandium aluminum nitride (ScAIN) or other Group III-Nitride transistor structure fabricated on the single crystal base. In these embodiments, each channel filter comprises a multi-layered ScAIN structure comprising one or more a single-crystal epitaxial ScAIN layers fabricated on the single crystal base. The ScAIN layers for each channel filter may be based on desired frequency characteristics of an associated one of the RF channels.
