Abstract

Mejoras en amplificadores de ondas eléctricas caracterizado porque comprenden dos válvulas termoiónicas que tienen sus rejillas y un dispositivo que conecta el ánodo de la primera de dichas válvulas al cátodo de la segunda válvula, estando dicho dispositivo diseñado de modo que cuando está combinado con las capacidades inter electrodo adaptado para pasar una banda de frecuencia de ancho especificado, siendo la imágen de admitancia de salida de dicho filtro a la banda media de frecuencia igual ala componente de conductancia de la admitancia cátodo-rejilla de control de dicha segunda válvula a aquella frecuencia cuando el ánodo de esta válvula está conectado a un dispositivo similar a dicho dispositivo o a una carga equivalente.Improvements in electric wave amplifiers characterized in that they comprise two thermionic valves that have their grids and a device that connects the anode of the first of said valves to the cathode of the second valve, said device being designed so that when combined with the inter electrode adapted to pass a frequency band of specified width, the output admittance image of said filter being at the middle frequency band equal to the conductance component of the cathode-control grid admittance of said second valve at that frequency when the anode of this valve is connected to a device similar to said device or to an equivalent load.
