Abstract: A guided acoustic wave resonant device is provided. The device comprises at least two filters (F1, . . . , Fi, . . . , FN), each filter comprising at least two acoustic wave resonators (R11- R12, . . . , Ri1-Ri2, . . . , RN1-RN2), each filter having a useful frequency band (BF1, . . . , BFi, . . . , BFN) centred on a central frequency (f1, . . . , fi, . . . , fN), each resonator comprising at least one suite of inter-digitated upper electrodes exhibiting a periodic structure of period (?ij) and a layer of piezoelectric material, each resonator having a coupling coefficient (k21, k22, . . . , k2n) and a resonant frequency (fr1, . . . , fr2, . . .
