摘要： An inductor that adjust characteristics of a transmit filter circuit is disposed so that the inductor and at least one of common paths, a matching circuit, a receive filter circuit, and receive paths connected to an output terminal of the transmit filter circuit define a propagation path due to magnetic-field coupling and/or electric-field coupling. This configuration does not require the addition of a circuit device to define the propagation path. It is thus possible to improve attenuation characteristics for an RF signal outside the frequency band of a transmitting signal and to improve isolation characteristics between a transmit filter circuit and a receive filter circuit without increasing the size of a radio-frequency module.

摘要： In an electronic component, a peripheral portion of an external terminal electrode is thicker than a center portion thereof, and at least a portion of the peripheral portion is buried in a component main body. A surface of the external terminal electrode and a principal surface of the component main body are located on the same plane. An electrically insulating coating layer is arranged along the principal surface of the component main body so as to cover at least a portion of the peripheral portion of the external terminal electrode. An end portion of the coating layer is in contact with a thickest portion of the peripheral portion of the external terminal electrode in the principal surface of the component main body. The coating layer and the surface of the external terminal electrode are located on the same plane.

摘要： In a circuit module, even if a transmission signal output from a transmission electrode of a mounting substrate to a transmission terminal of a splitter leaks into a ground electrode, the transmission signal that has leaked into the ground electrode flows into via conductors that are connected along an edge portion of the ground electrode close to the transmission electrode and connected to a ground line of a motherboard. Therefore, the transmission signal that has been output from the transmission electrode and leaked into the ground electrode is prevented from traveling along an edge portion of the ground electrode toward a reception electrode side. Thus, characteristics of isolation between the transmission electrode and the reception electrode provided on the mounting substrate on which the splitter is mounted are improved.
