Abstract

An integrated package provides contactless communication through a coupling mechanism embedded in the package. Package types include Surface Mount Technology (SMT), Low Temperature Co-fired Ceramic (LTCC) technology, and dual-in-line integrated circuit pressed ceramic packages generally. The package can include an acoustic wave device (AWD) sensor such as a surface acoustic wave (SAW) device or a bulk acoustic wave (BAW) device. Coupling includes inductive and capacitive effects through plates, loops, spirals, and coils. Coil inductance and SAW capacitance can be parallel resonant at the desired SAW resonance with the coil impedance higher than the SAW impedance, minimizing load-pull effects.
