Abstract

Patente de Invenção: "AMPLIFICADOR DE BAIXO BARULHO COM GANHO COMUTADO E MéTODO". Um amplificador de freq³ência de rádio de baixo barulho é comutável entre um estado de baixo ganho e um estado de alto ganho. Um primeiro transistor de emissor comum é ativo no estado de alto ganho e inativo no estado de baixo ganho. O primeiro transistor tem uma base acoplada a uma entrada de freq³ência de rádio e uma primeira entrada de polarização, um emissor acoplado à terra, e um coletor acoplado a uma saída de freq³ência de rádio amplificada. Um segundo transistor de base comum é ativo no estado de baixo ganho e inativo no estado de alto ganho. O segundo transporte tem um emissor acoplado à entrada de freq³ência de rádio, uma base acoplada a uma segunda entrada de polarização, e um coletor acoplado à saída de freq³ência de rádio amplificada.
