Abstract

1/1 resumo dispositivo sem fio de múltiplas antenas com amplificadores de potência que têm diferentes características é revelado um dispositivo sem fio com 5 amplificadores de potência tendo diferentes características para suportar transmissão em múltiplas antenas. esses amplificadores de potência podem ter diferente ganho, diferentes níveis máximos de potência de saída, etc. para satisfazer às exigências de diferentes sistemas sem fio. em 10 um modelo exemplar, um aparelho inclui primeiro e segundo amplificadores de potência tendo características diferentes. o primeiro amplificador de potência amplifica um primeiro sinal de entrada e provê um primeiro sinal de saída para uma primeira antena. o segundo amplificador de 15 potência amplifica o primeiro sinal de entrada ou um segundo sinal de entrada e provê um segundo sinal de saída para uma segunda antena, por exemplo, em um modo mimo ou em um modo de diversidade de transmissão. apenas o primeiro ou segundo amplificador de potência amplifica outro sinal de 20 entrada e provê outro sinal de saída à primeira antena, por exemplo, em um modo cdma ou em um modo gsm.
