Abstract

A triplexer and a multilayered structure thereof. The triplexer comprises a first filter circuit and a low pass filter circuit connected in parallel to an input terminal, and a second filter circuit and a third filter circuit connected in parallel to an output terminal of the low pass filter circuit. The first filter circuit passes a signal of a first frequency band, and the low pass filter circuit passes a signal of a predetermined frequency band which is lower than the first frequency band. The second filter circuit extracts a signal of a second frequency band from the predetermined frequency band signal, and the third filter circuit extracts a signal of a third frequency band from the predetermined frequency band signal, which third frequency band is lower than the second frequency band. The low pass filter circuit includes a notch circuit for extending a portion of the predetermined frequency band, neighboring the first frequency band. According to the invention, the triplexer can separate an input signal received at the input terminal into the signals of the first, second and third frequency bands.
