Abstract

This paper surveys X-Parameter based characterization
of surface acoustic wave (SAW) and bulk acoustic wave
(BAW) components. Due to the increased integration of frontend
modules in mobile devices, the power density in BAW and SAW
components rises continuously. Furthermore, the demand for
more frequency bands is required by advanced communication
techniques. As a result, the probability of significant nonlinear
emissions disturbing adjacent channels increases. Thus, the
linearity of individual frontend components becomes more and
more important. In order to comply with spectral emission masks
and limitations on spurious emissions imposed by standards
and specifications, accurate modeling of the device’s response
is required. In this paper, two measurement setups which
are based on a nonlinear vector network analyzer (NVNA) are
utilized in order to characterize BAW and SAW filters. A high
dynamic range is required because of the low power levels of the
generated higher order harmonics. Two different measurement
setup approaches are compared to each other. The application
of frequency selective attenuators enables an increase of the
dynamic range by more than 40 dB.
