Abstract

Un receptor de conversion descendente directa combina una senal RF recibida y una senal de oscilador local (LO) para formar una senal combinada. La senal de oscilador local tambien se encuentra desplazada de fase por aproximadamente 90 grados para formar una senal de cuadratura. Un mezclador forma el producto de la senal combinada y la senal de cuadratura para producir una senal de salida de banda base.
