Abstract
"CIRCUITO DE SAìDA DE AMPLIFICADOR DE POTêNCIA PARA UMA UNIDADE DE RáDIO MóVEL DE BANDA DUPLA, E, PROCESSO PARA OPERAR UM CIRCUITO DE SAìDA DE AMPLIFICADOR DE POTêNCIA PARA UMA UNIDADE DE RáDIO MóVEL DE BANDA DUPLA". Para suprimir, efetivamente, harmónicos em um telefone móvel de banda dupla com um amplificador de potência (10) e enviando sinais de transmissão para diferentes bandas de freq³ências (GSM; PCS; DCS) por intermédio de uma única saída conforme descrito; um circuito de saída de amplificador de potência em que os harmónicos são filtrados através de transformação de impedância de uma impedância de desligamento de uma unidade de comutação transmissora/ receptora (36,38). Aqui, a filtragem desejada dos harmónicos pode ser obtida quase sem gastos adicionais.
