Abstract
Mejoras en sistemas cambiadores de frecuencia caracterizado porque comprenden una válvula diodo y una válvula que tiene cátodo, un ánodo y por lo menos un electrodo de rejilla intermedia, en el que dicha válvula últimamente mencionada está dispuesta como oscilador y los cátodos de ambas válvulas están conectados a un punto de potencial constante sobre una conexión común que incluye un circuito oscilante sintonizado a la frecuencia de oscilación o a un armónico de la misma, y en el cual el circuito de señal de entrada y el circuito de salida de frecuencia intermedia están conectados al ánodo del diodo.Improvements in frequency changer systems characterized in that they comprise a diode valve and a valve having a cathode, an anode and at least one intermediate grid electrode, in which said last-mentioned valve is arranged as an oscillator and the cathodes of both valves are connected to a point of constant potential over a common connection that includes an oscillating circuit tuned to the frequency of oscillation or a harmonic thereof, and in which the input signal circuit and the intermediate frequency output circuit are connected to the anode diode.
