Abstract

Conmutador para sistemas de difusión por cable que comprende un diodo directamente conectado a la base de un transistor, formando el diodo, el transistor y la conexión entre ellos parte de una trayectoria de señales entre terminales de entrada y salida del conmutador, y un dispositivo de estado sólido para controlar selectivamente el potencial de la conexión entre el diodo y el transistor para hacerles conductores o no conductores.
