Abstract
A method for simultaneously modeling acoustic and electromagnetic (EM) behaviour of thin-film BAW RF filters is described. The inclusion of EM effects is important for fully understanding both passband loss and stopband rejection. Two lumped equivalent-circuit EM models are described. These are compared with measurement of solidly-mounted resonator (SBAR) filters up to 10 GHz.
