Abstract
RECEPTOR MULTICANAL DE FRECUENCIA INTERMEDIA. APLICABLE A LA RECEPCION DE SEÑALES ELECTRICAS DE RADIOFRECUENCIA PARA PASARLAS A FRECUENCIA INTERMEDIA, SIENDO INTEGRABLE EN SISTEMAS DE RADARES DE BANDA "L". CUENTA CON VARIOS CANALES (1) DE RECEPCION IGUALES E INDEPENDIENTES QUE DISPONEN DE ELEMENTOS DE PROTECCION, SUPERVISION Y AISLAMIENTO DE FALLOS. ADEMAS INCLUYE UN MODULO INTERFACE DE SEÑALES DE CONTROL Y CHEQUEO (2), UN REPARTIDOR DE SEÑAL DE OSCILADOR VARIABLE (3), UN REPARTIDOR DE SEÑAL DE OSCILADOR FIJO (4), Y UNA FUENTE DE ALIMENTACIONES (5) QUE PROPORCIONA LAS TENSIONES ADECUADAS A LOS DISTINTOS BLOQUES DE CIRCUITOS. CADA UNO DE LOS CANALES (1) SE CONSTITUYE BASICAMENTE MEDIANTE UNA ETAPA DE RADIOFRECUENCIA (6) CONECTADA A UNA ETAPA DE PRIMERA CONVERSION (7) A LA QUE SE UNE UNA ETAPA DE SEGUNDA CONVERSION (8), CUYA SALIDA PERMITE OBTENER LA SEÑAL DESEADA.
