摘要： In a circuit module in which a plurality of non-reciprocal circuit elements, each of which does not have a yoke, are mounted, the occurrence of magnetic coupling between the non-reciprocal circuit elements is significantly reduced and prevented. Core isolators are not arranged such that, in a state in which the direction of magnetic flux and the direction of magnetic flux are the same, the core isolators are aligned in the direction of the magnetic flux. Specifically, the core isolators generate the magnetic flux from left to right. The core isolators are aligned so as to be inclined relative to the magnetic flux. Thus, extension of the magnetic flux through the core isolator in a state of being directed in the same direction as that of the magnetic flux is significantly reduced and prevented.

摘要： In a duplexer module, a transmitting signal is correctly monitored without deteriorating receiving sensitivity. The duplexer module includes a transmission line, a reception line, and an antenna common line, and performs conversion between a transmission signal and a reception signals and antenna common signals. A transmission filter is inserted into the transmission line, and the transmission filter allows the transmission signal to pass therethrough and stops the reception signal. A reception filter is inserted into the reception line, and the reception filter allows the reception signal to pass therethrough and stops the transmission signal. A first line of a coupler which detects the transmitting signal is inserted into the transmission line at a stage subsequent to the transmission filter.
