Title (EN) RF FILTER WITH REDUCED INSERTION LOSS
(FR) FILTRE RF À PERTE D'INSERTION RÉDUITE
Abstract: front page image
(EN)The invention relates to an RF filter with reduced insertion loss. The filter (F) includes a first bandpass filter (BPF1) having a passband, a circuit unit (SE) having an undesired excitation at a critical frequency (fs) and a reflector (R) that reflects RF signals of this frequency before the circuit unit is undesirably excited and the power is lost as a result.
(FR)L'invention concerne un filtre RF à perte d'insertion réduite. Le filtre (F) comprend un premier filtre passe-bande (BPF1) ayant une bande passante, une unité de circuit (SE) ayant une excitation non souhaitée à une fréquence critique (fs) et un réflecteur (R) qui réfléchit les signaux RF de cette fréquence avant que l'unité de circuit ne soit excitée de manière indésirable et que la puissance ne soit perdue en conséquence.
