Abstract

La invencion propone un arreglo de amplificador de RF de ganancia variable, cuya impedancia de entrada es esencialmente independiente de la ganancia seleccionada, que tiene un gran numero de amplificadores elementales seleccionables, con una senal de entrada que se gradua y la impedancia de entrada se ajusta a la misma por medio de elementos de limitacion de corriente conmutables en direccion hacia la cabeza del cable de los amplificadores elementales, que estan asociados con los amplificadores elementales. El circuito tambien tiene una bajo nivel de ruido, el cual es ampliamente independiente de la ganancia seleccionada, y buena linealidad. Tambien se refiere a un receptor de radiodifusion asi como a un receptor para recibir senales de datos utilizando un amplificador de acuerdo a la invencion.
