Abstract

SE DESCRIBE UN CONVERSOR DE FRECUENCIA DE LA SUPRESION DE FRECUENCIA IMAGEN QUE ESENCIALMENTE TIENE UN BALUN (DIV) UTILIZADO COMO UN DIVISOR DE POTENCIA PARA ACOPLAR UNA SEÑAL OSCILADORA LOCAL A LOS EXTREMOS DE DOS MEZCLADORES DE FRECUENCIA (MIX1, MIX2). DICHOS MEZCLADORES (MIX1, MIX2) TIENEN PUERTOS A LOS QUE LLEGAN O DE LOS QUE SALEN SEÑALES DE FRECUENCIA INTERMEDIAS. LA INVENCION CONSISTE SOBRE TODO EN LA INTEGRACION DEL DIVISOR DE POTENCIA (DIV) Y LOS MEZCLADORES (MIX1, MIX2) EN UNA ESTRUCTURA PLANAR BASADA EN UN NUEVO CONCEPTO SUMINISTRADO EN UNA MICROCINTA Y EN UNA LINEA COPLANAR.
