Abstract

"CIRCUITO DE RECEPçãO E SISTEMA DE CONJUNTO DEANTENAS ADAPTATIVAS". Um circuito de recepção inclui umaseção de recepção e uma seção de controle. A seção derecepção realiza conversão de freq³ência de um sinal de entradausando um sinal de freq³ência local gerado por operação decomparação de fase. A seção de controle remove um erro de fasede passagem, adicionado na seção de recepção, com base em umsinal de comparação de fase fornecido a partir da seção derecepção. Um sistema de antena de arranjo adaptativo também édivulgado.
