Abstract

Un circuito amplificador de banda amplia para altas frecuencias tales que las capacidades inter-electródicas de tubos electrónicos resulten importantes teniendo dicho circuito un primer tubo de entrada por rejilla y un segundo tubo de entrada por cátodo cuyos tubos pueden estar en la misma ampolla estando la rejilla del segundo tubo puesta a tierra en esencia para potenciales de señal caracterizado porque el acoplamiento para señales desde el ánodo del primer tubo al cátodo del segundo tubo comprende un circuito resonante en serie que tiene baja impedancia a frecuencia dentro de la banda de paso del circuito amplificador teniendo dicho circuito resonante en serie inductancia y capacidad conectadas en serie estando su punto común conectado al cátodo del segundo tubo; consistiendo dicha capacidad al menos en parte en la capacidad cátodo-tierra del segundo tubo con lo cual es proporcionada para el segundo tubo una entrada de gran impedancia.
