Abstract
A high-frequency module includes at least first and second signal circuits that are each connected between a common antenna port and at least first and second signal ports. The first signal circuit includes a first inductor connected in series between the antenna port and the first signal port, a first capacitor connected in series between the first inductor and the first signal port, and a second inductor connected in shunt between the first capacitor and the first signal port. Series resonance is produced between the first inductor, the first capacitor, and the second inductor at a frequency within the frequency band of a target signal of the second signal circuit.
