About my definition of Q factor: The cartoon you label the parameters on is a 2-port filter trace. However the Q I cited applies to a 1-port trace of an individual resonator. The QORVO "filter fab" that I mention is not a filter fab. The real filter fab is in Florida and this image is apparently that of a packaging fab in China. Thanks to viewer Thomas for pointing this out.
