摘要：
Resonator coupling coefficient plays a key role in determining the bandwidth of acoustically or electrically coupled resonator filters. This paper presents a method using high mechanical impedance electrodes to increase the effective coupling coefficient for bulk acoustic wave (BAW) resonators in the solidly mounted resonator (SMR) or membrane (FBAR) configurations.
