Microwave (MW) impedance of a square-shaped piezoelectric (PE) resonator containing an AlN film with tilted c – axis and high temperature superconducting (HTS) electrodes was modelled for the case of propagation of longitudinal and shear acoustic waves (AW) across the resonator thickness. External DC magnetic field B was assumed to be applied perpendicularly to the resonator surface. It was shown, that the magnetic field results in a decrease of the resonance frequency and an increase of the MW losses. The effect is due to a change of the MW impedance of HTS component under action of the magnetic field.
