Title
(EN) SINGLE SUBSTRATE MULTIPLEXER
(FR) MULTIPLEXEUR À SUBSTRAT UNIQUE
Abstract
(EN)
At least three acoustic filters circuits FC are arranged on a single chip CH. At least two of them are electrically connected already on the chip for multiplexing. This reduces space consumption and leads to smaller device size.
(FR)
Selon l'invention, au moins trois circuits de filtres acoustiques FC sont disposés sur une puce unique CH. Au moins deux d'entre eux sont électriquement connectés sur la puce pour le multiplexage. La consommation d'espace et la taille de dispositif sont ainsi réduites.
