Abstract
There is provided a bandpass filter for a differential signal applicable to a device having a wide passband, being a device for transmitting a signal using a differential signal. Respective linesandand linesandare provide on two surfaces Pand Pat an inner layer of a dielectric body. Each two lines are arranged symmetrically about the same plane of symmetry C, and the length of each line is a quarter wavelength at the center frequency of a used band. Reference numeralsandare input/output ends of the linesand, andandare input output ends of linesand. Opposite ends to the input output ends are open. If a differential signal is input to terminals, a differential output appears at the terminals. This device works as a bandpass filter.
