Abstract

"DISPOSITIVO DE AMPLIFICAçãO DE POTêNCIA LINEAR COMBINADO E PROCESSO DE CONTROLAR O MESMO". Um dispositivo e um processo para combinação de saídas de uma pluralidade de amplificadores de potência linear enquanto prevenindo perda de sinais. O dispositivo de amplificação de potência linear combinado, incluindo: um módulo divisor de potência (150) que tem trajetos conectados respectivamente entre um terminal de entrada e uma pluralidade de terminais de saída e chaves conectadas respectivamente a cada um dos terminais de saída para divisão de potência de uma entrada de sinal de RF ao módulo divisor de potência e respectivamente dando saída a potência dividida aos terminais de saída; um módulo combinador de potência (300) que tem trajetos conectados respectivamente entre uma pluralidade de terminais de entrada e um terminal de saída e as chaves conectadas respectivamente a cada um dos terminais de entrada, para combinação de potência de uma entrada de sinal de RF ao módulo combinador de potência e dando saída a potência combinado; e amplificadores de potência linear (200) que são conectados entre os terminais de saída do módulo divisor de potência e os terminais de entrada do módulo combinador de potência, para linear amplificação do sinal de RF dividido em potência no módulo divisor de potência por esse meio dando saída ao sinal linear amplificado ao módulo combinador de potência, e na geração de um estado falho dos amplificadores de potência linear, o amplificador falho abrindo o trajeto do sinal de RF afetado pelo desligamento das correspondentes chaves no dito módulo divisor de potência e dito módulo combinador de potência.
