摘要： In a high frequency module, in addition to a main transmission path in which a high-frequency signal propagates in first filter elements, a sub transmission path is defined by inductive coupling or capacitive coupling between a first inductor and a matching element or by inductive coupling between the first inductor and a second inductor. The sub transmission path has different amplitude characteristics and phase characteristics from those of the main transmission path depending on a degree of the inductive coupling or capacitive coupling, and transmission characteristics as a high-frequency module are adjustable by adjusting the amplitude characteristics and the phase characteristics of the sub transmission path.
