Title (EN) BAND PASS FILTER AND FILTER CIRCUIT COMPRISING SAME
(FR) FILTRE PASSE-BANDE ET CIRCUIT FILTRANT LE COMPORTANT
Abstract:
(EN) A band pass filter comprises a series circuit of a first basic resonator section (BSl, BS2, BS3), a series capacitor (CS) and a second basic resonator section (BS4). Each basic resonator section comprises a parallel resonator and a series resonator.
(FR) L'invention concerne un filtre passe-bande comportant un circuit série d'un premier résonateur parallèle (RP), d'un condensateur série (CS) et d'au moins une section de résonateur de base (BS). Chaque section de résonateur de base comporte un résonateur parallèle (RP) et un résonateur série.
