Challenges of on-wafer characterization of BAW filter harmonics
Challenges of on-wafer characterization of BAW filter harmonics Susanne Kreuze, Member of Technical Staff, BAW R&D, Qorvo The constant demand for continuing RF module and thus bulk acoustic wave (BAW) filter size reduction results in the need of accurate design characterization strategies to comply with ever more stringent linear and non-linear product specification requirements. While the target performance
