Abstract

Aparato de generación de energía de frecuencia de microondas, provisto de unos medios de conversión de tensión. Incluye un cátodo para emitir electrones, una primera rejilla para controlar y enfocar el flujo de electrones emitidos desde el cátodo, una estructura de reactancia para que sirva de condensador, definiendo el cátodo, la primera rejilla y la estructura de reactancia una cavidad de entrada que actúa como un circuito resonante. También incluye una resistencia reguladora, uno de cuyos extremos está conectado a la primera rejilla y cuyo otro extremo está conectado al cátodo, para inducir una tensión de polarización en la primera rejilla. Aplicable para eliminar varios imanes presentes en la técnica anterior, dotando al microondas de una estructura más simple, en la que se reduce la influencia de las armónicas y del ruido entre las rejillas, permitiendo hacer variar la producción de energía de frecuencia de microondas.
