In the present article, we propose a ferroelectric‐based frequency mixer capable of reconfigurable functioning, a key trait in multi frequency band coverage, based on the nonlinear dielectric properties of BaSn x Ti 1−x O 3 ceramics. According to the properties of BaSn x Ti 1−x O 3 solid solutions, an optimum composition was selected to demonstrate the applicability as a discrete passive mixer with a simple coplanar geometry. A prototype device, with four coplanar capacitors, connected in a circular electric circuit was built on the surface of the selected ceramic. In this configuration, mixing products of the pumping and working signals were obtained and characterized.
