| contents | This paper reports on Solidly-Mounted Bidimensional Mode Resonators (S2MRs) utilizing 30% Scandium-doped Aluminum Nitride on Silicon Carbide, operating near 16 GHz. Experimental results show mechanical quality factors up to 380, electromechanical coupling coefficients of 4%, and an overall Figure of Merit (FOM=Q *kt2) exceeding 15. Additionally, Q Bode calculation is reported along with an analysis of the piezoelectric energy confinement coefficient showing the impact of thickness-to-wavelength ratio on the acoustic wave confinement. Finally, the devices demonstrate power handling capabilities greater than 20 dBm while achieving close impedance matching to 50 Ohm. These features make them strong candidates for commercial, military, and harsh-environment applications like satellite communications (SATCOM) and Active Electronically Scanned Arrays (AESA). |
