High-frequency module having inductors disposed with directions of their polarities opposite to each other

摘要

A high-frequency module includes a mount board, a wave splitter chip mounted on one principal surface of the mount board and including a transmission filter and a reception filter, a first inductor chip mounted on one principal surface of the mount board and including an inductor, and a second inductor chip mounted on one principal surface of the mount board and including an inductor. The first and second inductor chips are disposed adjacent to each other and each has a polarity. The first and second inductor chips are disposed such that the polarities thereof are opposite to each other, as viewed from the reception filter.
