Abstract: A high-frequency electronic component includes a multilayer body including a first input/output electrode, a second input/output electrode, and a third input/output electrode, and a first input/output path and a second input/output path. The first input/output path includes a first inductor and a first capacitor. The second input/output path includes a second inductor and the first capacitor. The first input/output electrode is located at a position deviated from a symmetric axis along a short-side direction of one main surface of the multilayer body. A distance from the first input/output electrode to a winding portion of the first inductor is larger than a distance from the first input/output electrode to a winding portion of the second inductor, and an inductance of the first inductor is larger than an inductance of the second inductor.

Abstract: A band pass filter includes parallel resonators. An inductor of a first parallel resonator at an intermediate stage is divided into a first inductor and a second inductor connected in parallel with each other. The first inductor and an inductor of a second parallel resonator are in magnetic coupling with each other, and the second inductor and an inductor of a third parallel resonator are in magnetic coupling with each other.

Abstract: A circuit substrate includes a substrate body, an input signal line conductor with which the substrate body is provided and included in an input path, a first mounting portion provided on a main surface of the substrate body, included in a first output path and on which a high-pass filter including a lumped-parameter element is mounted, at least one first output signal line conductor with which the substrate body is provided and included in the first output path, and a second mounting portion provided on the main surface of the substrate body, included in a second output path and on which a low-pass filter including a lumped-parameter element is mounted. The first output signal line conductor provided farthest upstream in a signal propagation direction is connected to the input signal line conductor via a first lumped-parameter element mounted on the main surface of the substrate body.
