Abstract

"ARQUITETURA DE AMPLIFICADOR PARALELO UTILIZANDO-SE TéCNICAS DIGITAIS DE CONTROLE DE FASE". Um método e aparelho melhorados para utilizar amplificadores paralelos para amplificar eficientemente um sinal de informação são revelados. O aparelho melhorado utiliza técnicas de manipulação de sinal digitais ao otimizar a fase dos sinais de entrada convertidos em freq³ência (upconverted) providos a cada um dos amplificadores paralelos. A fase e a amplitude dos sinais de entrada são ajustadas de forma que a potência medida na saída de um combinador (402) seja maximizada ao ser comparada à soma da potência dos sinais de entrada do combinador (120).
