Considerations on nonlinearity measurement with high signal-to-noise ratio for RF SAW/BAW devices SAW/BAW

چکیده
Introduction of new communication standards makes specifications given to RF surface and bulk acoustic wave (SAW/BAW) devices tougher and tougher. For example, futher improvement of the device linearity is demanded without increasing the device size. Nevertheless, it is still unclear where and how the non-linearity occurs. For finding origin(s) of the very weak non-linearity, its measurement system must possess excellent linearity, large signal-to-noise ratio (SNR) and low feedthrough level. This paper discusses the setup of the non-linear measurement system for RF SAW/BAW devices.
