Abstract:
1. A cavity resonator, comprising: a dielectric element having one or more dielectric layers; a shielded enclosure overlying at least a portion of said dielectric element, said shielded enclosure enclosing a first volume and a second volume and having a metallic divider separating the first volume from the second volume; a first unitary trace disposed within the first volume, said first unitary trace including a first transmission line trace having a major surface extending along a surface of said dielectric element and a first inductor trace having a major surface extending along a surface of said dielectric element; and a first reference trace extending along said dielectric element and separated from said first transmission line trace of said first unitary trace by at least one dielectric layer of said dielectric element; a second unitary trace disposed within the second volume, said second unitary trace including a second transmission line trace having a major surface extending along a surface of said dielectric element and a second inductor trace having a major surface extending along said surface of said dielectric element; and a second reference trace extending along said dielectric element and separated from said second transmission line trace of said second unitary trace by at least one dielectric layer of said dielectric element; wherein said metallic divider has an opening adapted to permit a predetermined proportion of energy of an electromagnetic field excited by the first inductor trace to be coupled onto the second inductor trace.
