Abstract

Un aparato transmisor/receptor empleado ventajosamente en un sistema de comunicacion de radio para transmision y recepcion de radio de señales multiplexadas en division de frecuencia o multiplexadas en division de tiempo del sistema doble de division de frecuencia al conmutar entre diversas antenas. El aparato transmisor/receptor incluye una pluralidad de antenas para transmision/recepcion de radio de las señales de recepcion y transmision, un interruptor para conmutar entre las antenas, una pluralidad de multiplexores de antena conectados a las antenas a través del interruptor y que tienen bandas de frecuencia diferentes respectivas, una unidad de transmision conectada a los multiplexores de antena, una unidad de recepcion conectada a los multiplexores de antena y una unidad de control para controlar el interruptor, la unidad de transmision y la unidad de recepcion. La unidad de control controla el interruptor de manera que una opcional de las antenas se conecte al multiplexor de antena de la banda de frecuencia utilizada en comunicacion de radio unicamente mediante la conmutacion. La unidad de control controla la unidad de recepcion durante la recepcion para recibir señales de recepcion a través del multiplexor de antena desde la antena opcional, mientras que controla la unidad de transmision durante la transmision para transmitir señales de transmision de la frecuencia usada para transmision de radio a través del multiplexor de antena desde la antena opcional.
