Nonlinear frequency mixing in spin-wave transducers — •Matthias Wagner, Felix Kohl, Björn Heinz, and Philipp Pirro — Fachbereich Physik and Landesforschungszentrum OPTIMAS, RPTU Kaiserslautern- Landau, D-67663 Kaiserslautern, Germany

The demand for higher data transmission rates and high level of miniaturization has drawn attention to spin waves as a potential platform for building future radio frequency devices. So far, a lot of research has been carried out in optimizing prototype devices solely relying on continuous single-frequency operation. Nevertheless, the question how spin-wave transducers perform when real, multi-frequency signals are applied still is an open research subject that is especially relevant in the high-power regime where nonlinear spin-wave scattering leads to intermixing of frequency components within the passband. In this study, we quantify the nonlinear distortions caused by two-tone signals in spin-wave transducers by measuring relevant parameters, such as the 1-dB compression point and the third-order intercept point. Our results enable direct comparison between spin-wave based devices and conventional RF technology at the application level.
