Abstract: front page image
(EN)A variable filter circuit (10) comprising a serial arm (11) connected between ports (P1-P2), a parallel arm (12) including a resonator (Re_p1) connected in series between ports (P1-P3), and a parallel arm (13) including a resonator (Re_p2) connected in series between ports (P2-P3). The serial arm (11) includes an inductor (Ls1) connected between ports (P1-P2). The parallel arms (12, 13) include variable capacitance elements (Cs_p1, Cs_p2) connected in series to the resonators (Re_p1, Re_p2).
(FR)L'invention concerne un circuit de filtrage (10) qui est équipé d'une branche en série (11) connectée entre des ports (P1-P2), d'une branche en parallèle (12) incluant un résonateur (Re_p1) et connectée en série entre les port (P1-P3), et d'une branche en parallèle (13) incluant un résonateur (Re_p2) et connectée en série entre les port (P2-P3). La branche en série (11) inclut une bobine inductrice (Ls1) connectée entre les ports (P1-P2), et les branches en parallèle (12, 13) incluent des capacités variables (Cs_p1, Cs_p2) connectées en série aux résonateurs (Re_p1, Re_p2).
(JA) ポート(P1-P2)間に接続された直列腕(11)と、ポート(P1-P3)間に直列に接続された共振子(Re_p1)を含む並列腕(12)と、ポート(P2-P3)間に直列に接続された共振子(Re_p2)を含む並列腕(13)と、を備え、直列腕(11)は、ポート(P1-P2)間に接続されたインダクタ(Ls1)を含み、並列腕(12,13)は、共振子(Re_p1,Re_p2)に対して直列に接続された可変容量(Cs_p1,Cs_p2)を含む、可変フィルタ回路(10)。
