Abstract

UN CIRCUITO DE MEZCLADOR DE IF (10) EN UN RECEPTOR DE EJECUCION EN CIRCUITOS INTEGRADOS EMPLEA UN PAR DE MEZCLADORES DE EQUILIBRIO DOBLE (22, 46), UNO INYECTADO CON UNA SEÑAL DE REFERENCIA DE OSCILADOR LOCAL EN FASE, MIENTRAS QUE LA FASE DE CANDICATURA DE LA SEÑAL DE REFERENCIA SE INYECTA AL SEGUNDO MEZCLADOR. UN CIRCUITO DE CAMBIO DE FASE (42) AÑADE OTRO CAMBIO DE FASE DE 90 LES EN FASE Y FUERA DE FASE SE APLICAN A UN CIRCUITO SUMADOR (40) PARA ATENUAR PRODUCTOS MEZCLADORES NO DESEADOS Y REFORZAR LA SEÑAL IF DESEADA. LOS ELEMENTOS EQUILIBRADOS DEL CIRCUITO DE CAMBIO DE FASE DE 90 ALES RESISTENCIAS DE EMISOR Y COLECTOR, UN TRANSISTOR CONECTADO A UN DIODO (63) EN SERIE CON LA RESISTENCIA DE CARGA DE COLECTOR (65), Y UN CAPACITADOR COLECTOR A BASE (67), QUE PROPORCIONA UN CAMBIO DE FASE DE AMPLITUD CONSTANTE EN UNA ESTRUCTURA DE GANANCIA UNITARIA INDEPENDIENTE DE LA CORRIENTE, PARA PRODUCIR UN CAMBIO DE FASE PRECISO DE 90 . LA CORRIENTE DEL EMISOR SE PUEDE AJUSTAR PARA COMPENSAR LA VARIACIONDE PRODUCCION EN EL VALOR ABSOLUTO DE LA RESISTENCIA FIJADA, POR EJ, VARIANDO LA CORRIENTE EN EL TRANSISTOR Y EN EL DIODO, LA RESISTENCIA DINAMICA, COMPENSE LA VARIACION DE LA RESISTENCIA FIJADA.
