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.
