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.
