Abstract

EL CONMUTADOR ESTA REALIZADO POR MEDIO DE DOS VIAS AMPLIFICADORAS REGULABLES DE TRANSISTORES. LOS COLECTORES DE LOS TRANSISTORES DE SALIDA (T1, T1B) ESTAN REUNIDOS, SIN DISPOSITIVO DE ADAPTACION DE IMPEDANCIA PROPIA A CADA VIA, EN UN PUNTO COMUN (10) Y A ESTE NIVEL UN DISPOSITIVO DE ADAPTACION DE IMPEDANCIA (L5,R7) ES COMUN A LAS DOS VIAS. ESTE CONMUTADOR ES UTILIZADO NOTABLEMENTE PARA SELECCIONAR VIAS DE SEÑAL ENTRE 1 Y 2 GHZ EN LOS SITEMAS DE RECEPCION DE TELEVISION POR SATELITE.
