Abstract
A compact multilayer band-pass filter using an interdigital capacitor which can be integrated into a compact form in a relatively low frequency band. The band-pass filter filters only a signal of a predetermined frequency band from a signal applied through an input terminal, and outputs a filtered signal to an output terminal. The band-pass filter includes at least one pair of transmission lines, respectively formed between the input terminal and the output terminal provided on an uppermost layer, for generating an inductor component, a capacitance compensation unit, with the interdigital capacitor having a plurality of layers, for loading a specified capacitance to one end of the transmission line, and a ground layer coupled to a specified layer of the capacitance compensation unit and the other end of the transmission line and formed on a lowermost layer.
