Abstract: front page image
(EN)This variable filter circuit (10) is provided with: a parallel arm (11) connected between a port (P3) and a connection point (A); a series arm (12) containing a resonator (Re_s1) connected in series between a port (P1) and the connection point (A); and a series arm (13) containing a resonator (Re_s2) connected in series between a port (P2) and the connection point (A). The parallel arm (11) contains a first inductor (Lp1), and the series arms (12, 13) contain variable capacitors (Cp_s1, Cp_s2) connected parallel to the resonators (Re_s1, Re_s2).
(FR)La présente invention concerne un circuit de filtre variable (10) qui comporte : une branche en parallèle (11) connectée entre un port (P3) et un point de connexion (A) ; une branche en série (12) contenant un résonateur (Re_s1), connectée en série entre un port (P1) et le point de connexion (A) ; et une branche en série (13) contenant un résonateur (Re_s2), connectée en série entre un port (P2) et le point de connexion (A). La branche en parallèle (11) contient un premier inducteur (Lp1), et les branches en série (12, 13) contiennent des condensateurs variables (Cp_s1, Cp_s2) connectés en parallèle avec les résonateurs (Re_s1, Re_s2).
(JA) ポート(P3)-接続点(A)間に接続された並列腕(11)と、ポート(P1)-接続点(A)間に直列に接続された共振子(Re_s1)を含む直列腕(12)と、ポート(P2)-接続点(A)間に直列に接続された共振子(Re_s2)を含む直列腕(13)と、を備え、並列腕(11)は、第1のインダクタ(Lp1)を含み、直列腕(12,13)は、共振子(Re_s1,Re_s2)に対して並列に接続された可変容量(Cp_s1,Cp_s2)を含む、可変フィルタ回路(10)。
