Abstract

Un radio (100) que tiene un ciclo de fase asegurada (CFA) (207), y un ciclo de control automático de frecuencia (CAF) (215, 109,111) combinados y método para operarlo. Una mezcladora (201) convierte la señal de RF recibida (117) en una señal de frecuencia intermedia (F1) (219) que responde a una señal de inyección (217). El CFA (207) asegura la señal de inyección (217) a la señal de RF recibida (117), en respuesta a una señal de referencia (119). El ciclo de CAF (215, 109, 111) asegura la señal de referencia (119) a la señal de inyección (217).
