Abstract

APARELHO PARA VERIFICAR UMA TENSãO DE SAìDA DE BLOCO DE BAIXO RUìDO. A presente invenção diz respeito a conjunto de circuito de diagnóstico de sistema para sistemas de antena com componentes de antena ativos. Mais especificamente, a presente invenção revela um aparelho compreendendo uma conexão (710) entre uma antena e uma fonte de alimentação que conduz uma primeira tensão CC, uma fonte de um sinal modula do pela largura de pulso (730), um filtro passa-baixa para converter (R3,Cl) o sinal modulado pela largura de pulso a uma segunda tensão CC, e um comparador para comparar (740) a primeira tensão CC e a segunda tensão CC e gerar um sinal de saída responsivo à diferença entre a primeira tensão CC e a segunda tensão CC.
