The utilization of spin-wave transducers for radio frequency signal processing provides significant potential due to intrinsic tunability, scalability, and nonlinearity. However, signal interference with electromagnetic leakage can add further complexity for signal processing. Here, we experimentally identify the electromagnetic crosstalk (EM) as a major source of interference induced distortion and provide an analytic model based on the coherent interference of spin-waves and electromagnetic leakage to predict the impact on device operation. In addition, we test multiple transducer geometries to identify operational regimes and minimize the EM impact. Finally, the effect of nonlinear device operation on the interference is addressed, which is of relevance for the exploitation of the spin-waves intrinsic nonlinear traits.
