Abstract

UNA INDUCTANCIA VARIABLE UTILIZABLE EN UNA RED O MALLA DE CIRCUITOS DE RF DE SINTONIA RAPIDA COMPRENDE UNA PLURALIDAD DE CIRCUITOS CONMUTADORES DE INDUCTANCIA CONECTADOS EN SERIE. CADA CIRCUITO CONMUTADOR DE INDUCTANCIA INCLUYE UN TERMINAL DE ENTRADA CONECTADO A UNA BOBINA DISCRETA DE INDUCTANCIA (18B) Y A UN DIODO PIN (24B), E INCLUYE UN TERMINAL DE SALIDA CONECTADO A UNOS CONMUTADORES QUE A SU VEZ VAN CONECTADOS A LA BOBINA DISCRETA DE INDUCTANCIA (18B) Y EL DIODO PIN (24B), CONECTADOS EN PARALELO ENTRE SI. EL DIODO PIN (24B) FUNCIONA, SEA EN LA MODALIDAD DE POLARIZACION DIRECTA PARA DESCONECTAR LA RESPECTIVA BOBINA DISCRETA DE INDUCTANCIA (18B), SEA EN LA MODALIDAD DE POLARIZACION INVERSA PARA INTERCALAR O RECONECTAR LA RESPECTIVA BOBINA DISCRETA DE INDUCTANCIA (18B). EL DIODO PIN (24B) ES POLARIZADO EN SENTIDO DIRECTO O INVERSO POR UNOS CONMUTADORES A BASE DE MOSFET (36A, 36B) (38A, 38B), UNO DE LOS CUALES TIENE UN CONDENSADOR PARASITO UTILIZADO PARA PROPORCIONAR UNA TENSION DE POLARIZACION INVERSA, RECTIFICADA Y CARGADA, AL DIODO PIN (24B) A FIN DE ASEGURAR EL FUNCIONAMIENTO DE LA POLARIZACION INVERSA DURANTE AMPLIOS CAMBIOS DE TENSION EN LAS SEÑALES DE RF CONDUCIDAS. FIGURA 4.
