Abstract

PURPOSE:To form a lattice type ceramic filter which has high yield and the reduced number of man-hours of manufacture by installing one serial piezoelectric ceramic resonator and one parallel piezoelectric ceramic resonator of every basic section L in one case. CONSTITUTION:A serial resonator (S element) 11 and a parallel resonator (P element) 12 are arranged in every basic L-section circuit of the lattice type ceramic filter and installed in a case 15 together with an electrode plate 13 with a projection and a cushion 14 having insulation effect at proper positions, and cases 15 corresponding to the necessary amount of attenuation are arrayed in series. Thus, the disorder of the element arrangement in a manufacture process is eliminated and cases are replaced, one with one, to reduce the number of man-hours for waveform adjustment.
