Abstract

<B> MISTURADOR DE FAIXAS MúLTIPLAS COM OSCILADOR LOCAL COMUM <D> Um misturador (100) inclui dois elementos transistores (313, 324), cada um provido por uma faixa de freq³ência. Um oscilador local simples provê um sinal a cada terminal de cada elemento transistor. Os sinais de comunicação para cada faixa de freq³ência, chegam a cada um dos respectivos elementos transistores, em um outro terminal. Um terceiro terminal de cada elemento transistor é conectado à saída.
