Abstract

Mejoras en osciladores de alta frecuencia de válvula de vacio del tipo cuya válvula de vacía comprende un cátodo, una rejilla, un ánodo y una pantalla rodeando a dichos electrodos, y en que las capacitancias inter-electródicas y electrodo-pantalla son de valor apreciable con las frecuencias a generar caracterizado por la combinación de medios para conectar dicho cátodo directamente a la referida pantalla, un conductor catódico reactivo que conecta dicha pantalla y cátodo a tierra, un primer condensador, una resistencia, medios para conectar dicha resistencia y condensador en paralelo entre la mencionada rejilla y tierra, un segundo condensador, un conductor anódico reactivo y medios para conectar en serie dicho segundo condensador y conductor anódico reactivo entre el mencionado ánodo y tierra.Improvements in vacuum valve high-frequency oscillators of the type whose vacuum valve comprises a cathode, a grid, an anode and a screen surrounding said electrodes, and in which the inter-electrode and electrode-screen capacitances are of appreciable value with the frequencies to be generated characterized by the combination of means to connect said cathode directly to said screen, a reactive cathode conductor that connects said screen and cathode to ground, a first capacitor, a resistor, means to connect said resistor and capacitor in parallel between said grid and ground, a second capacitor, a reactive anode conductor and means for connecting in series said second capacitor and reactive anode conductor between said anode and ground.
