Title: RECEPTION FILTER, DEMULTIPLEXER, AND COMMUNICATION DEVICE
Abstract:
A reception filter according to the present invention includes: a reception terminal for outputting a reception signal coming from an antenna terminal; a second DMS filter, serving as a longitudinally coupled dual-mode-type elastic-wave filter, located in a signal path from the antenna terminal to the reception terminal; a fourth GND terminal to which a reference potential is applied; and a fourth GND wire connected to the fourth GND terminal and the second DMS filter. A reception terminal conductor, which is composed of the reception terminal and a reception terminal wire connected to the reception terminal, and a fourth GND conductor, which is composed of the fourth GND terminal and the fourth GND wire, are disposed adjacent to each other and are capacitively coupled.
