Abstract

PARA DETERMINAR EL PUNTO DE OPERACION DE UN AMPLIFICADOR NO LINEAL 2 DE UN CANAL DE COMUNICACIONES 1, POR EJEMPLO DE UN TRANSPONDEDOR DE UN SATELITE DE COMUNICACIONES, UNA PRIMERA SEÑAL DE ENTRADA I 1 SE TRANSMITE A TRAVES DEL CANAL DE COM UNICACIONES 1 A UN NIVEL DE POTENCIA P I1 QUE LLEVA AL AMPLIFICADOR NO LINEAL 2 A UN MODO DE OPERACION NO-LINEAL. ADEMAS UNA SEGUNDA SEÑAL DE ENTRADA I 2 SE TRANSMITE A TRAVES DEL CANAL DE COMUNICACIONES 1 SIMULTANEAMENTE CON LA PRIMERA SEÑAL DE ENTRADA I 1 . LA SEGUNDA SEÑAL DE ENTRADA I 2 SE TRANSMITE A UN NIVEL POR DEBAJO DEL NIVEL DE LA PRIMERA SEÑAL DE ENTRADA I 1 . SI LA CONTRIBUCION DE LA SEGUNDA SEÑAL DE ENTRADA I 2 A LA ENTRADA TOTAL DEL AMPLIFICADOR NO LINEAL ES PEQUEÑA, EL PUNTO DE OPERACION DEL AMPLIFICADOR NO LINEAL SE DETERMINA CASI UNICAMENTE POR LA PRIMERA SEÑAL DE ENTRADA. DE AHI, LA POTENCIA DE SALIDA P O2 QUE CORRESPONDE A LA SEGUNDA SEÑAL I 2 SE DETERMINA CON MAS FUERZA POR LA POTENCIA DE ENTRADA P I1 DE LA PRIMERA SEÑAL I 1 . EL PU NTO DE OPERACION (P I , P O ) DE DICHO AMPLIFICADOR NO LINEAL (2) SE DETERMINA SOBRE LA BASE DE UNA SEÑAL DE SALIDA (O 2 ) DE DICHO CANAL DE COMUNICACIONES (1) QUE CORRESPONDE A DICHA SEGUNDA SEÑAL (I 2 ).
