Abstract

Un filtre d'encoches hybride comprend un réseau d'inversion d'impédance raccordé à un réseau de filtrage à deux connexions. Dans sa forme la plus simple, le réseau d'inversion d'impédance comprend des inverseurs d'impédance d'une admittance caractéristique de pratiquement ?2, raccordés entre les entrées et les sorties auquel le réseau de filtrage à deux connections est raccordé, et des inverseurs d'impédance d'une admittance caractéristique pratiquement égale à l'unité qui interconnectent les inverseurs d'impédance à admittance caractéristique de ?2 à leurs extrémités respectives. Le réseau de filtrage à deux connexions peut être constitué de plusieurs résonateurs connectés en série et il est lui-même connecté aux sorties du réseau d'inversion d'impédance. Ce filtre d'encoches hybride peut prendre la forme d'un filtre d'encoches hybride commuté grâce à un commutateur placé entre une paire de résonateurs adjacents dans le réseau de filtrage.
