HIGH FREQUENCY FILTER CIRCUIT AND STACKED CERAMIC FILTER

摘要

PURPOSE: A high frequency filter circuit and a stacked ceramic filter are provided to reduce insertion losses and achieve improved inhibit characteristics. CONSTITUTION: A high frequency filter circuit comprises a first capacitor(C1) and a second capacitor(C2) connected in serial between an input terminal(IN) and an output terminal(OUT); a first inductor(L1) connected in parallel to the serial circuit of the first and second capacitors; and a second inductor(L2) and a third capacitor(C3) connected in serial to the ground from the contact of the first and second capacitors.
