Abstract

UN TRANSCEPTOR DE RADIO QUE TIENE CARACTERISTICAS DE EQUILIBRADO DE IMPEDANCIA MEJORADAS ENTRE UNA ANTENA DE TIPO VARILLA Y PARTES DE TRASMISION Y RECEPCION CONSIGUIENTES. SE DISPONE UN CIRCUITO DE EQUILIBRADO DE IMPEDANCIA ENTRE LA ANTENA Y EL DUPLEXOR PARA AJUSTAR LA IMPEDANCIA ENTRE LOS MISMOS A UNA FRECUENCIA DENTRO DE UNA BANDA DE FRECUENCIA DE SEÑAL DESEADA. UNA SEÑAL DE TRANSMISION Y UNA SEÑAL DE RECEPCION PUEDEN TENER FRECUENCIAS BASICAMENTE DIFERENTES EN CUYO CASO EL CIRCUITO DE EQUILIBRADO DE IMPEDANCIA OPERA PREFERENTEMENTE EN FRECUENCIAS CENTRALES DE ESTAS SEÑALES, RESPECTIVAMENTE. EL CIRCUITO DE EQUILIBRADO DE IMPEDANCIA INCLUYE UN PRIMER INDUCTOR INSERTADO ENTRE LA ANTENA Y EL DUPLEXOR, UN PRIMER CONDENSADOR INSERTADO ENTRE EL POTENCIAL DE TIERRA Y LA ANTENA Y UN CIRCUITO DE RESONANCIA PARALELO COMPUESTO DE UN CIRCUITO PARALELO Y UN SEGUNDO CONDENSADOR Y UN SEGUNDO INDUCTOR INSERTADO ENTRE EL DUPLEXOR Y EL POTENCIAL DE TIERRA.
