Аннотация: The article presents the results of measuring the generation of the second harmonic in a microstrip transmission line and in a quarter-wavelength stepped-impedance microstrip resonator with a thin permalloy magnetic film (Ni80Fe20). The measurements were carried out for three samples with different thicknesses - 50 nm, 75 nm and 100 nm, at an input signal excitation frequency of 1 GHz and maximum input power of ~3500 mW. It was shown that the level of the second harmonic rises as the TMF thickness increases. It was found that a 100-nm sample generates the second harmonic more efficiently due to the larger ΔHFMR and the larger amount of magnetic material involved in the process of nonlinear conversion of the input power. It was shown that the resonator-based frequency doubler has a conversion factor ~4500 times higher than that of the doubler based on the microstrip line due to the higher value of the loaded Q-factor. Therefore, a quarter-wavelength stepped-impedance microstrip resonator can be used as a frequency doubler. © 2022 IEEE.
