Abstract: A communication device includes a first radio frequency circuit; a plurality of second radio frequency circuits; and a power division/combination network, including a signal combining port and a plurality of signal dividing ports, where the signal combining port is coupled to the first radio frequency circuit, and the plurality of signal dividing ports is coupled to the plurality of second radio frequency circuits. The power division/combination network includes a power divider/combiner. Two ends of a first signal transmission network in the power divider/combiner are coupled to a common port and a first dividing port respectively, two ends of a second signal transmission network are coupled to the common port and a second dividing port respectively, and a mode tuning circuit is coupled to the first signal transmission network.
