The present invention provides for a method and apparatus to control non- adjacent cross-coupling in a micro-strip filter. In instances of weak cross- coupling, such as a filter circuit on a high dielectric constant substrate material (e.g., LaAIO3, with dielectric constant of 24), a closed loop is used to inductively enhance the cross-coupling. The closed loop increases the transmission zero levels. For strong cross-coupling cases, such as a filter circuit on a lower dielectric constant substrate material (e.g., MgO with dielectric constant of 9.6), a capacitive cross-coupling cancellation mechanism is introduced to reduce the cross-coupling. In the latter instance, the transmission zero levels are moved down.

La présente invention concerne un procédé et un appareil destinés à commander le couplage croisé non adjacent dans un filtre microruban. Dans les cas de faible couplage croisé, tels qu'un circuit de filtre sur un matériau de substrat à constante diélectrique élevée (par exemple LaAIO¿3? avec une constante diélectrique de 24), une boucle fermée est utilisée pour augmenter de manière inductive le couplage croisé. La boucle fermée augmente les niveaux des zéros de transmission. Dans les cas de fort couplage croisé, tel qu'un circuit de filtre sur un matériau de substrat à faible constante diélectrique (par exemple, MgO à constante diélectrique de 9,6), un mécanisme d'annulation du couplage croisé capacitif est introduit pour réduire le couplage croisé. Dans ce dernier cas, les niveaux de zéros de transmission sont abaissés.
