摘要

A composite high frequency component which can be used in three different communication systems and a mobile communication apparatus which includes the same are provided. The composite high frequency component includes a first high frequency switch having a first common port and first, second, and third communication ports. The first communication port is connected to the transmitting sections of first and second communication systems. The second communication port is connected to a receiving section of the first communication system. The third communication port is connected to a receiving section of the second communication system. The composite high frequency component also includes a second high frequency switch having a second common port and fourth and fifth communication ports. The fourth communication port is connected to a transmitting section of a third communication system. The fifth communication port is connected to a receiving section of the third communication system.
