Abstract

"CIRCUITO DE CONTROLE DE SAìDA DE POTêNCIA APERFEIçOADO EM UMA ESTAçãO MóVEL E PROCESSO DE CONTROLE DE POTêNCIA DE SAìDA EM UMA ESTAçãO MóVEL". Um circuito de controle de saída de potência aperfeiçoado é utilizado em uma estação móvel possuindo um transmissor incluindo um amplificador de ganho variável de transmissor desenvolvendo um sinal de saída de RF aplicado a uma antena. O circuito de controle de saída de potência aperfeiçoado inclui um circuito detector para retificar um sinal de entrada para produzir uma saída de CC representando o nível de potência do sinal de sáida. Um circuito de amostragem é conectado ao transmissor e ao circuito detector para conectar e desconectar, alternadamente, o sinal de RF do transmissor para o circuito detector, por meio do que o circuito detector desenvolve um sinal de saída de CC alternado. Um amplificador de CA de ganho variável é acoplado ao circuito detector para amplificar a saída de detector. Um circuito de controle de ganho é acoplado ao amplificador de CA para receber a saída de detector amplificada e compará-la a uma referência selecionada, para desenvolver um sinal de retro-alimentação utilizado para variar o ganho do amplificador de CA para manter um nível desejado de saída constante, o sinal de retro-alimentação representando potência de saída de transmissor. Um comparador compara o sinal de retro-alimentação a uma referência de controle para controlar o ganho do amplificador de ganho variável de transmissor.
