Abstract

"DISPOSITIVO E PROCESSO PARA CONTROLAR UM NIVEL DE POTêNCIA DE SAìDA EM UM TERMINAL DE COMUNICAçãO MóVEL". Um dispositivo e processo para controlar um nível de potência de saída em um terminal de comunicação móvel. O dispositivo inclui um detector de RSSI para detectar uma intensidade de um sinal recebido a partir de uma estação base, e um controlador possuindo uma memória para armazenar os valores de controle de voltagem de polarização e os valores de controle de corrente de polarização correspondente às intensidades dos sinais recebidos, onde o controlador lê o valor de controle de voltagem de polarização e o valor de controle de corrente de polarização correspondentes em resposta à intensidade de sinal detectada e supre os valores lidos para um amplificador de potência.
