Abstract
filtro de radiofrequência de alto desempenho harmônico. é divulgado um filtro de radiofrequência, rf, que integra verticalmente um filtro de ondas acústicas com um filtro de dispositivo passivo integrado, ipd. o filtro de ondas acústicas fornece seletividade na banda de frequência fundamental, enquanto o filtro ipd fornece rejeição nas bandas de frequências harmônicas. o filtro de ondas acústicas compreende áreas de contato (415) e no topo uma camada de passivação (420). o filtro ipd é formado no topo da camada de passivação (420) com capacitores mim de si3n4 em suas camadas metálicas inferiores (512, 522) e indutores em suas camadas metálicas superiores (530,540). as camadas metálicas são separadas e cobertas por camadas isolantes de poli-imida (525,535,545). os contatos externos (555,550) são realizados no topo das camadas ipd.
