Abstract
Provided is a band pass filter constituted by a printed circuit board (PCB) and a multi-layer ceramic chip (MLCC) to be mounted in a circuit, without additional parts such as a low temperature co-fired ceramic (LTCC) based filter, and so on, and it is an object to produce a band pass filter constituted by an inductor formed of a PCB pattern and a capacitor formed of an MLCC to implement a high performance and compact band pass filter. The band pass filter includes an inductor pattern part formed of a plurality of PCB patterns and having inductance; an MLCC part constituted by a plurality of MLCCs mounted in a lower end side of the inductor pattern part and having a capacitance; and a port part formed of a plurality of PCB patterns and connected to the PCB patterns extending from the inductor pattern part.
