Further reduction of nonlinearity is demanded in RF SAW/BAW devices, but even their generation mechanisms have not been fully understood. Although phase possesses comparable information to amplitude, it has not been paid much attention in the nonlinear signal measurement. Nonlinear vector network analyzers (NVNAs) may be used for the purpose. However, NVNAs have limited linearity than spectrum analyzers (SAs), and it seems to be very complex to apply NVNAs for the measurement of intermodulation distortion (IMD). |
