STACK BAND PASS FILTER

摘要

PURPOSE: A stack band pass filter is provided to be capable of designing a resonator structure without limitation by realizing distributed elements with a planar circuit using a stack ceramic technique. CONSTITUTION: A stack band pass filter has an input terminal(1) and an output terminal(2) and a pair of resonators(10) which are curved to have a predetermined shape and are installed to be opposite to each other. Each capacitor(C) is formed between each resonator and a ground(G). The resonators has such a structure that one side is opened, and the input terminal and the output terminal are formed at the opened portion.
