Abstract

"MéTODO PARA OPERAR UM TRANSMISSOR DE MODO DUAL RF E RF EDGE DE MúLTIPLOS INTERVALOS DE TEMPO, E, TRANSMISSOR RF". Um método é descrito para operar o transmissor RF de modo dual de múltiplos intervalos de tempo, sendo que o transmissor RF inclui uma unidade de controle que opera de acordo com o método. O método inclui, antes do primeiro intervalo de tempo, estabelecer uma pluralidade de sinais de controle para o transmissor RF de acordo com o primeiro formato de modulação usado durante o primeiro intervalo de tempo; e durante o período de guarda entre o primeiro e o próximo intervalo de tempo, o intervalo de tempo temporariamente adjacente, estabelecer uma pluralidade de sinais de controle para o transmissor RF de acordo com o segundo formato de modulação usado durante o segundo intervalo de tempo, onde o primeiro formato de modulação difere do segundo formato de modulação. Em uma incorporação preferida, um dos formatos de modulação é o 8-PSK que usa o amplificador de potência no modo de ganho fixo, o outro dos formatos de modulação é o GMSK que usa o amplificador de potência no modo de ganho variável, um de uma pluralidade de sinais de controle estabelece o modo de ganho do amplificador de potência e é inclinado durante o período de guarda, e o outro de uma pluralidade de sinais de controle estabelece uma corrente quiescente do amplificador de potência.
