For example, the LTE LB circuit and the GPS circuit are respectively provided with a filter circuit, so that a second harmonic generated by the LTE LB circuit is filtered out in the LTE LB circuit, and a received fundamental wave generated by the LTE LB circuit is filtered out in the GPS circuit, thereby reducing interference to the GPS.
