ABSTRACT:
A multi-band high-frequency circuit for performing wireless communications among pluralities of communication systems having different communication frequencies. A high-frequency switch circuit contains: switching elements for switching the connection of pluralities of multi-band antennas to transmitting circuits and receiving circuits; a first diplexer circuit disposed between the high-frequency switch circuit and transmitting circuits for branching a high-frequency signal into frequency bands of the communication systems; and a second diplexer circuit disposed between the high-frequency switch circuit and receiving circuits for branching a high-frequency signal into frequency bands of the communication systems.
