Abstract
El proceso y el aparato de la presente invencion limitan la potencia de salida de un radio en respuesta a la temperatura de los componentes importantes del radio. Unos sensores de temperatura (1025) miden la temperatura de los componentes y envían las señales de temperatura a la circunferencia de control de potencia (1030). La poetencia de transmision se mide (1020) a la salida de amplificador de potencia (1015). A medida que aumenta la temperatura, la circuitería de control de potencia (1030) reduce la potencia de transmision a fin de reducir la temperatura de los componentes importantes. La potencia de supervisa de manera que no se reduzca por debajo del nivel de potencia requerido por las normas.
